Forms Data Controls :: DataGrid ButtonColumn Not Executing OnItemCommand?
Jan 12, 2010
I am building a query tool which displays the results in a dataGrid. when the results are displayed (buttonColumn) it should allow the user to click a row and execute another function. the columns selected in my query are not always the same name but it is user defined, therefore i am not able to define the columns in the ASP page, but insted am doing it in the C# class behind. When the table is generated it does have the button columns but when clicked it does a postback and it does not execute the function defined in the OnItemCommand tag.
DataGrid Code in aspx page:

I am having a DataGrid in one usercontrol which is getting filled with some data when I press some button(ouside it). This Datagrid is filled by one linkbutton also. When I click this LinkButton then OnItemCommand or SelectedIndexChanged should fire, but both the events are not firng. While the control's PageLoad event is firing.

I'm working on a bug in our application and I cannot figure out why this problem even exists. We have a custom DataGrid control that inherits from the standard asp.net DataGrid. In the grid, we have a ButtonColumn as the second to last column. The code for that column is:
[Code]....
The problem is that the "alt" text does not show up at all. There are 2 other images in this DataGrid, and the alt text shows up just fine in those.

I'm having some real problems trying to do this. In simple, a table shows a list of rooms with details of the room in each column, extracted from a database. The there is a button in the repeater, which is supposed to tell me what I clicked on in a new label. However the OnItemCommand just doesn't seem to be working.
[Code]....
Right now I'm just trying to get it to work, so that when I press the button, it causes the label to say "It works". But it just doesn't want to work.

Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.
[URL]
I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.

I have this strange problem with IE7I have my form with 2 DataGrid controls in an update panel. the first column in both grids are "buttonColumns".the seccond grid appears after i select a row in first grid...so far everything is ok. If i select a row from seccond grid by hitting the firs collumn cell, my page resets all page setting...including page.isPostback property(page.isPostback becomes false) so all my data are initialized from page_load function. All these are happening only in IE7. Can anybody tell why this happens?

I have a templated user control with single instance template attribute. It works great for everything except the following scenario:
[Code]....
The folder selector uses a tree view that allows people to select a folder, its FolderSelected event works perfectly and the file selector updates with the files. The file selector has a repeater that lists the files in the selected directory. It has a linkbutton for each of the files so that the user can select a file. The problem is that the ItemCommand event of the repeater doesn't fire when the file name is clicked on. The page performs the async postback like it should, but in debug, the method to handle the itemcommand event is never hit. On the same user control to select files there is a button that the user can add files to the folder. When it is clicked, the event DOES fire and the file is added and the control refreshes in the update panel, everything perfect. It seems that because the linkbutton is already in a templated control (which is in a user control, in a templated control), the event isn't firing correctly. I am confused as to why this should be a problem, especially since all the other events (even the custom ones) fire as long as they aren't in another templated control. Since the code is complicated, I didn't want to post it all here.

I want to execute code written in a dropdown selectedindexchanged event from some another user defined function.
For this i m writing:
ddlMyDropDown1_SelectedIndexChanged(sender, e);
It works when use it in page_load (means the code in ddlMyDropDown1_SelectedIndexChanged is executed) but when i write the same line in another function it gives error "The name sender doesnot exists in current context".

I have a datagridview control that I'm using to display cache data to the end used on a web form. The issue that I'm having is that every time I re-run the application, and the cache data is re-generated... it loads duplicate data that's being displayed to the end user. I can't seem to figure out how to keep this from happening.
What I would like to have happen is that only unique data rows be returned and cached for the end user. Unless there are new data rows on the database that needs to be included in the cache data results...the previous data results should not be duplicated. I've tried to change a few properties on the datagridview control, but nothing seem to keep this from happening.
