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'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 RepliesI've following gridview:
<asp:Panel ID="pnlScroll" runat="server" ScrollBars="Auto">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">

Now I am not able to understand why the OnRowCommand event is not firing. Nothing is happening on clicking the button in gridview.
I have several Gridviews that display data from the same table. They are separate for visual effect (Different characteristics). If I select on an item from any grid they can all execute the same code (Show Details).I'm using a row command GridViewCommandEventArgs.Is it possible/How can you get the gridview name from the row command so that I can use just one subroutine.
Sub GV_RowCommand(ByVal sender
As
Object, ByVal e
As GridViewCommandEventArgs)
If e.CommandName = "select" Then
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
Dim row As GridViewRow = ????.Rows(index)
In the last cell of my gridview I have 2 separate linkbuttons. I want to further process them using Gridview Onrowcommand event but How would I know which particular link has actually raised the event.
View 3 RepliesI 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.

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!!!
it does not fire the event even i have set it directly in the gridview
here is the code in my app_code page

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 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 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.

I'm workin in VS2008. I want to display a gridview with product details and when user clicks on product image, details of that image will be displayed in another page. I've used GridViewCommandEventArgs but it is not working. Here is my code:

I have a gridview set up as follows:

Now, as you can see I've set up the commandargument, and was expecting to get to that in my code behind file. My code is as follows:
[Code]....
Ok...so far so good, and as long as I'm the only one working on the system it works fine. The problem is if this scenario happens:
* I go to the page and look at the gridview
* Someone else enters a new record into the database, causing the first row to contain a new record (not displayed in my browser)
* I click select.
What happens then is that, for some odd reason, I will get n numbers higher than the one I actually selected (n = num_added -num_removed).
I was under the impression that the commandargument wouldn't change for my session as long as I didn't refresh the gridview...?... There are no ajax or anything else messing with postbacks or viewstate as far as I can see..
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.

For a given MS SQL Database table of staff members, I'm using ASP to display each record line by line as follows:
So I've added 2 ImageButtons in an extra column and the problem I have is passing the record id as a CommandArgument to redirect to a secure page where the record can be edited or deleted.
Here's some code:
[Code]....
[Code]....
ctdRdr(0) evaluates to the ID value for the the record. )
When I click on the 'Delete' ImageButton the URL in the Response.Redirect becomes:
ctdirectory_secure/deletemember.aspx?id=<%@%20ctdRdr(0)%>
instead of, say:
ctdirectory_secure/deletemember.aspx?id=435
I'm assuming that a <%= expression %> cannot be used to set a control parameter, but how else can I do it?
I have a ListView and I'm using the option <InsertItemTemplate>. Inside this template I have two control: TextBox and Button.
I'm having tourble in C# to read the CommandArgument of my button OnCommand event:
What am I doing wrong?
protected void AddComment(object sender , CommandEventArgs e)
{
string Args = e.CommandArgument.ToString();
}
<asp:Button
ID="buttonComment"
OnCommand="AddComment"
CommandArgument='<%#
Eval("MyId")%>'
runat="server"
/>
I have a button inside a table in gridview templatefield and i want to access its row index value in row_command event
i used this line.
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
but got error .Input string was not in a correct format.
However i am able to fetch the row index value in button _click event using this line.
Dim index As Integer = (CType(CType(sender, Control).Parent.Parent, GridViewRow)).RowIndex
It becomes more and more complicated, how can I access the commandArgument of a LinkButton inside a ListView that is in a Accordion control?
View 5 Replieswhy the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?
View 3 RepliesI want to pass single character passed when i clicked in the linkbutton.
and how i access this at code behind file.
I have a repeater. This gets bound to a data set which contains (amongst others) a field called EntityType and a field called ID. An Entity Type might be "Person" and there might be several categories of "Person". The ID field identifies that category. So there might be a "Person" type 1, a "Person" type 2 and so on. The Entity Type and ID therefore make up a compound primary key.
Nested in each row of the repeater I have a grid view which get populated as a result of clicking an "expand" button in the repeater row. Each row in the GridView represents an "Entity". So "Peter" who's own ID might be, say 59 might be a "Person" of Type 1. So Peter really has a three column primary key consisting of the EntityType and ID field's from the repeater's dataset and the ID from gridview's dataset.
So in order to query the database and fully retrieve Peter, I need that whole primary key. I know how to get the ID from the GridView's dataset, I set Eval("ID") as the CommandArgument for the gridview's button and then consume it in the event. But I don't know how to get at the EntityType or the ID from the Repeater's dataset. How can I do that?
Here's my code at the moment:-
asp Code:
<asp:Repeater ID="ChildClassesRepeater" runat="server" OnItemCommand="ChildClassesRepeater_ItemCommand" Visible ="false" >
<ItemTemplate> <tr> <td> <%# DataBinder.Eval(Container.DataItem, "EntityType")%> </td> <td>
<%# DataBinder.Eval(Container.DataItem, "Class")%> </td> <td>
[Code] ....
I'm thinking the easiest thing to do is put the EntityType and parent ID on the Command Argument where it currently reads IDontKnowWhatGoesHere but I can't work out how to get at them.
Alternatively, is there a way I can get at them in the event handler? I think not but I'm not sure.
I could have the query for the grid view return the parent columns, that would allow me to eval them in the same way as I am the entity ID. That feels like I'm reading redundant data, though, as it's already there in the client - if I could just get at it.
I have a gridview with multiple rows, each has a Update button and I need to pass 2 values when someone clicks on Update button. Aside from packing the arguments inside CommandArgument separated by commas (archaic and not elegant), how would I pass more than one argument?
<asp:LinkButton ID="UpdateButton" runat="server" CommandName="UpdateRow" CommandArgument="arg_value" Text="Update and Insert" OnCommand="CommandButton_Click" ></asp:LinkButton>
As a note, the values can't be retrieved from any controls on the page, so don't offer any design solutions. Please concentrate on the question asked.
I have a dropdownlist outside the gridview control. My griview control also have dropdownlist in the first column. I want to populate the dropdownlist inside the gridview control for all rows when the selected item is changed in the outside dropdownlist.
