Assuming the data is loaded from SQL Server, GridView includes 5 columns as shown above, cells Search of textbox where you find out quickly (due to its use on the image for illustration), in his cell this search textbox enter any value in the column that has (according to this column 5), the GridView grid lines present value of the lookup value, usually looking to have a value equal to 1 column with which to look.
If you use fast search method does not need to specify one column before it, how to write this quickly find how to load into the GridView ?
I'm not entirely sure I understand your question but if your looking for a fast way to search the contents of a datagridview you can bind the SQL result to a bindingsource, use the bindingsource as the datagridviews data source and then set the binding sources filter to "dataproperty LIKE '%" + textBox1.Text + "%';"

Sorry if this isn't what you're asking for!

I'm building a searching sheet, which take a dropdown cell as input data. User can select from the list, or type in the key word. Searched data will be populated by rows/column with my query formula. The search result itself works just fine.
However, the drop down list doesn't.
Here's a picture of my search.
As you can see in the picture, autocomplete would only populate 6 items, while my search query produce much more, which is exactly what I need. It's clear enough : Autocomplete compare the whole text, not word - by - word.
Is there anyway to change this behavior ?
My sheet is for other people to look for a specific item. I cannot expect them to know what I have entered in my database and force them to search by those exact keywords.
Anything from script to formula is fine with me. I just need at least, a lead..
I'm currently working with Google Sheets to import data from Contact Form 7 in Wordpress. All the data is coming over fine, but I wanted to see about formatting it in more user friendly fashion. I've simplified the example a bit, but the gist of the form I have created allows the user to request multiple versions of a graphic file with different wording as needed, up to 5(my example has just 2 for simplicity sake).
All the data is imported using the CF7 variables and ideally I wanted to clean this up a bit. What I had thought of as a solution was creating a second sheet that pulls in this data submitted in the first sheet into a more user friendly format, as I intended to use this as a work form for a designer to create the requested graphic once the data is received. With each request the name/department/email/date all stay the same, but I'd like to display the version and line 1 and 2 data on another line. Is it possible to reorganize data like this on the fly, so when a new form is submitted and adds data to sheet 1, sheet 2 would then update with the properly formatted info?
Is this even possible to do? I did some looking online, but didn't anything that really related to this type of data manipulation.
Solution:
Here's what ended up working for my example
=ArrayFormula(QUERY({
Sheet1!A2:D,Sheet1!E2:G,ROW(Sheet1!A2:A);
IFERROR(LEN(Sheet1!A2:D)/0),Sheet1!H2:J,ROW(Sheet1!A2:A);
IFERROR(LEN(Sheet1!A2:D)/0),Sheet1!K2:M,ROW(Sheet1!A2:A);
IFERROR(LEN(Sheet1!A2:D)/0),Sheet1!N2:P,ROW(Sheet1!A2:A);
IFERROR(LEN(Sheet1!A2:D)/0),Sheet1!Q2:S,ROW(Sheet1!A2:A)
},"select Col1,Col2,Col3,Col4,Col5,Col6,Col7 where Col5<>'' order by Col8",1))
Yes, it's possible.
One way is to use arrays and the QUERY function.
For simplicity, let say that
Columns A and B have the general information of the order
Columns C and D have the data for version 1
Columns E and F have the data for version 2
Columns G and H have the data for version 3
On the output sheet, add the headers.
Below of them add a formula like the following:
=ArrayFormula(QUERY({A2:B,C2:D,ROW(A2:A);IFERROR(LEN(A2:B)/0),E2:F,ROW(A2:A);IFERROR(LEN(A2:B)/0),G2:H,ROW(A2:A)},"select Col1,Col2,Col3,Col4 where Col3<>'' order by Col5"))
References start on row 2 to skip the headers to avoid to include them on the output sheet.
ROW(A2:A) is used to keep the order
IFERROR(LEN(A2:B)/0) is a "trick" used to "hide" the order (general information) data for the second and following rows for the same order. On the select parameter of the QUERY function, it's referrey as Col5 on the order by clause.
It's assumed that lookup-choice-1 will never be empty.
NOTES:
If more columns were added, the column numbers should be updated accordingly
Don't use the order by clause to sort the result by the general information columns because the "trick" to hide the "labels". If you need to apply a sort, do it' before applying the above formula, you could do this by sorting the source range through the Data > Sort range... feature, so the data is sorted before it's transformed by the above formula.

I have an application that will load a CSV file containing two columns. At program load I need to have the first column as items in a combo edit control. Once the user selects (or enters a value) I need to populate a label with the value from the second column. My thought was to use an in memory data set, FDMemTable which would be loaded at form create. Then once the user selects, or enters an item, I would run a query to pull the description. I've tried but have been unsuccessful with the simple loading of the combo edit.
Is this the best way to achieve the desired results, and is there samples similar to what I'm looking to do?
Read the file.
Parse it into an array of name/value pairs.
Populate the combo drop down list with the names.
When the combo's selection is changed to a new index, read the value from the array using that index. Update the label.
Database tables and queries seem somewhat over the top for a single simple task like this.
I am trying to create a Delphi grid to allow display and edit in a db grid of data that might have a different data type on each row. I would like to display a specific control for each data type, e.g. when the data type is DateTime, I want to display my custom edit control that allows typing a date in or popping up a calendar.
The data looks something like this:
Name DataType DateValue StringValue BooleanValue
---------------------------------------------------------
A Date 1/1/2007
B String asdf
C Boolean True
...and in the db, this table has a column for each possible type of value. So, there is a BooleanValue column, DateValue, etc.
What I would like to do is display a single 'Value' column in the grid that displays the appropriate edit control depending on what the 'DataType' is for that row. So, the grid should look like :
Name DataType Value
---------------------------
A Date 1/1/2007
B String asdf
C Boolean True
It seems I will need to display a different edit control (to allow the user to edit the Value column) for each row dynamically based on the value of the DataType column. I know there are more advanced grids out there that handle this sort of problem, but the powers that be will not allow anything but what is available out-of-the-box with Delphi.
Any ideas on how to make something like this work?
Personally, I would not go for editing directly inside the TDBGrid in this case, since your Table is not DB normalized (I don't use it in any case actually). I would have used a Calculated field to display the desired value in the grid, And dynamically created the TDBxxxEdits on the form for each field type (How about your own TDBTreeEdit for example, a TDBRichEdit, or a DB Image pickup editor, etc...?).
In case you do want to use your own controls on the TDBGrid, and replace the default TInplaceEdit editor, you can refer the following article: Adding components to a DBGrid, and a related article: Displaying and editing MEMO fiels in Delphi's TDBGrid
Displaying all of the data in the same column is quite easy. You can simply add a calculated string field, and change the value according to what you are storing in that row.
The editing is quite a bit more complicated. If you want to have an in-place editor, you are in for a world of hurt... I've done it, it's a pain, and takes a lot of time. If you want to display a dialog to edit the value, that's much easier. You can add a column objects to the grid and you can setup the column you have attached to the calc field to display a button. When the button is clicked you simply display the editing dialog needed for that row, and commit the edits when the dialog is closed.
There are other ways to get this done, but I would say the above would be the shortest way. Other ways may include custom draw events to display your data in one column, intercept clicks to create your own editor, etc, etc, etc...
after add calculated fields .
Sample:
procedure OnCalculate(DataSet:TDataSet);
begin
case IndexText(DataSet['ValueType'],['Date','String','Boolean']) of
0:DataSet['DateValue']:=StrToDateTime(DataSet['Value']); // also converting
1:DataSet['StringValue']:=DataSet['Value'];
2:DataSet['BooleanValue']:= MatchText(DataSet['Value'],['1','True','T','Y','Yes']);
{etc datatypes}
end;
end;
So I'm messing around with a new project in Delphi 2009 and the default components that can be dropped onto a form for accessing data consist of a SQLConnection, DataSource and SQLQuery. If I add a simple select to the query component, say:
select name from customers
and then drop a DBComboBox on the form and link it up with the DataSource I get a single record in the combo box. After using Google for half and hour to figure out what I was doing wrong it looks like you have to manually add some code to your project which loops through the dataset and adds all the records to the drop down box. Something like:
while not SQLQuery.eof do
begin
DBComboBox.items.add(SQLQuery.fieldbyname('name').asstring);
SQLQuery.next;
end;
And that actually sort of works, but then you get a list in the drop down which you can't actually select anything from. Regardless of the result though I'm wondering why would you even use a DBComboBox if you have to manually add the result of your query to it? Seems to me that if it doesn't automatically populate the db combo box with the result of the query then we might as well be using a non-data-aware component like tcombobox.
I guess what I'm asking is why does it work this way? Isn't the purpose of data aware drag-and-drop controls to minimize the amount of actual written code and speed development? Is there a method that I'm missing that is supposed to make this easier?
A TDBComboBox doesn't get its list of values from the database; it gets its current value from the database. Link it to a field in your dataset, and when you change the active record, the combo box's current value will change. Change the combo box's current value, and the corresponding field's value will change.
If you want to get the list of values from the database as well, then use a TDBLookupComboBox.
This is all covered in the help:
Using TDBListBox and TDBComboBox
Displaying and Editing Data in Lookup List and Combo Boxes
Defining a Lookup List Column
I think you want the TDBLookupComboBox because that allows you to lookup from a list of items where the list comes from a dataset.
In the TDBComboBox, the list is just a TStrings manually filled with data.

DbCombox is a dbaware version of the standard combobox component.
