I have something simple but for some reason it's not working.
On my OnRowCommand I am doing a DataBind but for somereason my Grid always stays blank.
I chceked in the Debug and It gets the data fine
this.GridView1.DataSource = recruitmentTemplateCandidates; // there is data here.
GridView1.DataBind();
after that it goes to OnPreRender and then nothing shows up in the Grid. why is that?
I have a Gridview and on the OnRowCommand of that GridView I want to Bind the data for another Gridview, but everytime I do that nothing gets bound to the Second Gridview.
View 3 RepliesI'm using a standard GridView control inside of a web form. The web form uses a master page. The application is running within sharepoint (wss 3.0) environment. When i attach both the OnRowCommand and OnRowDatabound events to the gridview as shown in the markup below, only the OnRowDataBound event fires. The OnRowCommand never gets hit. When i press a button on a row, it posts back but never hits the onRowCommand event and simply falls through and repaints the page . However if i remove the OnRowDataBound event, the OnRowCommand event starts to fires correctly. I've tried a number of things...1. Hooking up the events in code instead of markup. (inside of PageLoad or PageInit)2. Changing the order in which the events are attached.
View 4 Replies i have a column in a gridview with an imagebutton in a column. i added an onclientclick event so that a html confirm dialog shows with ok and cancel button, so that if you click cancel, the event should not continue, but if you click ok, the gridviews onrowcommand should fire. The grid is as follows:

but when i click the button on the grid, the alert comes up and if i select ok, i get the following exception:

i have the following nested gridview
i could get the inner gridview onRowDataBound working by setting that directly in the gridview
but i cannot get the linkbutton's onrowCommad inside the inner gridview working!!!

here is the code in my app_code page

I have a gridview and I have a link button that fires the onrowcommand event. In the method I have
protected void SelectCreditCard(object sender, GridViewCommandEventArgs e)
{
int index = Convert.ToInt32(e.CommandArgument);
}
But I get the error input string in incorrect format.
I have a webpage with many updatepanels. Each panel contains databound controls including gridviews (GV). They are bound at runtime so the number of gridview columns varies with each bind. the controls are bound only once in Page_Load event ( within if (!Page.IsPostBack) )I added a linkbutton to each header in the GV in the RowDataBound event. Once the header is clicked, the event is handled in the OnRowCommand and it calls a method to bind the controls with new data.Things work fine if the GV is bound with every postback (no if (!Page.IsPostBack) condition) but I don't want to bind all the controls with every postbackMy problem is that the OnRowCommand is not fired if the GV is not bound on the postbackI even tried to add click handler for the linkbutton but that didn't work either.

Now I am not able to understand why the OnRowCommand event is not firing. Nothing is happening on clicking the button in gridview.
how to get the SelectedDataKey.Value when you have a button on your gridview that does not have the commandName="Select"? I already have the custom gridview select that have the commandName="select" and it works great to get the selected value and show my detailsview from the row selected. Now I want another button on my gridview that does a completely different action and actually does a page redirect, I just need to get the actual SelectedDataKey.Value only I made the commandName="View" or just something different from select becuase I don't want it to follow the same actions and event as select does.

I have the following structure 3 Dropdown Boxes, the 2nd and 3rd dependant on the 1st and when I change the first combo the pages refreshes with error I am assuming it's happening when posting back. I have nothing in my code behind file for this page so far.
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
This is a very Basic application that I am creating using Visual Basic and ASP.Net 3.5. Am using a SQL Datasource have searched for this error some of the answers seem extremely complex and I can't figure them out, surely a simple tasks like this has to be easy to bind back to the database from several drop down lists.
Problem is when ever i try to bind the gridview using the Sql data source and calling SP.
Its not displaying anything on the screen, where as i tested the SP, its working fine.
But when i write the Select statement in Sql data source... Its working fine.

I have a slight issue I awas trying to fix for 2-3 days, but nothing I try works.
The scenario:
DetailsView control in edit mode, I pass parameters to the SqlDataSourceProducts (edit.aspx?id=2) and the data source selects the appropriate data and fills in the DetailsView form.
Except two drop down lists. These two DDLs (DDL2 and DDL3) are dependent on the previous DDL (DDL1) in the DetailsView.
when the selected value of the DDL1 changes, DDL2 and 3 change their lists and get bound to the database.
The problem is: when I edit something from the database, DDL2 and 3 appear empty and when I update any other field and leave these, they get blanked in the database.
My goal is to set the selected value of DDL2 and 3 to the values in the database WHERE ID = QueryStringField="id".
I can go for not binding the data unless the field is changed, but does not sound professional and user friendly.
code:
The SqlDataSource used to select the parameters from the table and populate the DetailsView

I retreive data from database but not able to bind it to a repeater control. this is the error i get.

I've seen this before, I fixed long time ago and now cannot remember how I did :) My store procedure won't update the record because the sql field 'itemId' is being passed as ZERO always.
<EditItemTemplate>
<table border="0" width="100%">
<tr>

I have a gridview that I am using to host some data. Each row in the gridview links to a blob and I am using the SOnRowCommand event to click on the row and to stream the blob(which is an image) out as a file. This works fine. However when i implement paging on the gridview with the paging event the handler think it is an OnRowCommand event and executes the code behing the OnRowCommand handler and not the pageindex change event.
