So in this photo I have a gridview,
Column 1 is DropDownList, Column 2 is TextBox and Column 3 is Read Only. for Column 1 as a TextBox, when I clicked Edit, changed the value of TextBox and then I clicked Update, the Value of Column 1 chenged. Then I replaced TextBox from column 1 to a DropDownList. I converted Column1 into a TemplateField, Edited template field of column 1 and changed it as a DropDownList. Now When I try to Edit a Row, I choose another value from DropDownList and it doesn't change.
NOTE: I haven't don this programmatically. .aspx.cs file is empty. I have done this via GridView Tasks.
UPDATE:
I have managed to fix the problem.
On EditTemplateField, on DropDownList I clicked Edit Data Bindings
After that on Selected Value I bounded it to the column I want.

Scenarios:
Based on selection of a dropdown value and click of search button gridview to be binded. This datatable will have different table/column records based on selected value of a dropdown.
For ex :
If dropdown list value "Yes" is selected Column 1 to Column 6 to be bounded from table A where column 1 is a check box , column 2 is a bound field and column 3,5,6 is a textbox and column 4 is a dropdown
If dropdown list value "No" is selected Column 1,Column 4 to Column 8 to be bounded from table A where column 1 is a check box , column 4 is a bound field and column 6,7,8 is a textbox and column 5 is a dropdown

I have a datagridview and recently I got task to add a checkbox column (which I did) and a button (btnFilter) that will filter/show only selected rows so for example if I check only 4th, 5th and 6th row and click on 'btnFilter' the datagridview would show only rows 4,5 and 6.
So, the problem is how to show only selected (checkbox) rows.
Thank you for your time.
The idea is to have a button which when clicked, a loop will be executed over GridView Rows. Within the loop we will check whether the CheckBox for that row is checked, if the CheckBox is checked then the Value from the GridView Row Cell and Cell controls like Label, TextBox, DropDownList, etc. can be fetched.
Here is the complete example with screenshots and source code in C# and VB
GridView checkbox: Get Selected rows
I have a gridview with 100 Rows with paging turned on (showing 20 rows at a time).
There is a checkbox in each row to select that record.
In the header there is a "check all" checkbox
When I check it will just select the 20 from the current page.
Is there a way to have it select all 100 rows with out resizing the size of the page (have it show all 100 rows).
Thanks
Add a field checked in your datalist , and set its value according to the checked all checkbox.
You can have a property in that table which is bound to grid and you
can set this attribute when checkall is clicked and based on this
attribute the check box in each row can be rendered.
If you want to bind any functionality on all the rows in gridview, you can simply use dataview of the data source of the grid view on check all click. Or you can perform desired operation on the datasource(data table or dataset) on CheckAll checkbox checked
I have a GridView with columns "Item Code, Name, Quantity, Rate". I bind the values for this columns from textboxes, not from database. It means I am adding values to GridView at runtime. Then in button click or in rowdeleting event, I want to delete selected row from GridView at runtime. Would you please provide solution for this? Thanks in advance...
