Forms Data Controls :: Combining OnRowDataBound And OnRowCommand Events Causes OnRowCommand Not To Fire For GridView?
Jul 1, 2010
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.

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:
[Code]....
[Code]....
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 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 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.

<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.

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.
Here is my .cs

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.
[Code]....
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
DataTable dt = new DataTable();
dt = (DataTable)Session["data"];
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataSource = dt;
GridView1.DataBind();
}

In a GridView control ASP.NET
OnRowDataBound="gvTest_OnRowDataBound" followed by
protected void gvTest_OnRowDataBound(....){}
OR
Text='<%# BindMyData(DataBinder.Eval(Container,"DataItem.Price"), DataBinder.Eval(Container,"DataItem.CurrencyID")) %>'
followed by
protected string BindMyData(object price, object currencyID)
{...}
Which one is best in terms of performance and coding best practice?

All of my columns are bound in the Gridview. On OnRowDataBound event, I am adding some custom styles like underlines and colors to the text of the columns. Sorting of data is working fine but I am losing my custom styles when I sort. I am using the generic sorting code for the GridView.
How I can keep my custom styles on sorting that I added during OnRowDataBound event.

I've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.

I have a ListView control on a page that I need to support inline editing and inserting. Before I put it inside an update panel, everything was fine. As soon as I put it in an update panel, I seem to lose theOnItemUpdating, OnItemCanceling events. The OnItemEding event still fires, though.I am doing all updating, inserting manually.

I finally figured it out. It's quite a lot of code, so check out the zip!!I have a control, with multiple controls, which contain multiple checkboxes. ee pictureWhen pressing "Submit" I'd like, if any checkboxes have changed, to fire an event containing two Lists - one containing the checkboxes which check-mark were removed and one containing the checkboxes that's been checked.Hooking up on the CheckedChanged-event is no problem and currently I just add the checkboxes to the added/removed lists in their container, but when can I fire the event in the container with the populated lists?

I've got a problem with my onrowdatabound function. The situation is like this:
protected
void gvSQL_RowDataBound(Object sender,
GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
switch (Session["Filter"].ToString())
{
case "NonZero":
if (e.Row.Cells[9].Text == "0")
{
e.Row.Visible = false;
}
break;
}
}
}
At the end I need to kill the Session, so my plan is to detect if it reaches the last row. Then I can kill it. Does anyone know how to do this? Or is there someone that knows a better to fix this?

I'm building a library of custom controls. My controls are inherited from CompositeControl. Depending on the user's answer I have to insert more custom control. I have a PlaceHolder (_ph) passed in from the client code. I insert my controls into that PlaceHolder.
My problem is the control I inserted in the event handler does not fire its event, but it fires the parent event. For example, if I have an EddDropDown A, and the user picks an answer, I have to create EddDropDown B and C in edd_SelectedIndexChanged. When I pick an answer for B, it fires SelectedIndexChanged for A instead of B.
I think it has something to do with entering the page cycle late.
this is an example of my controls:
using System;
using System.Collections.Generic;
using System.Collections;
using System.Linq;
using System.Text;

I am trying to fire one event out of two avalible events based on a check box selectoin, I have already registered the two events in the page_load() and i check if the check box is checked (checkbox is located within a gridview) then i un-register one of the events and just keep one events registered as following(Only relative part is shown):
[Code]....
I am trying to fire one event only based on the checkbox selection. I tryed to debug and noticed that, in fact, both evetns always get fired starting first with Button_SessionStartOrEnd_StartSessino and then Button_SessionStartOrEnd_EndSessino. So how can i fire one event only? please note that my code to check if the ckeckbox is checked within the girdview works fine.

I am working on object data source and datagridview. I have given object data source to the grid view as the data source of grid. The issue which i m facing is that whenever i click on next page(like 2 or 3 or 1) it takes lot of time to fire. although it is fired but I have to wait a minute or two and then it fired.
Whenever I click any event(e.g. next page , page 5 ,3 or edit etc) of gridview it does not give response. If I wait for a minute then click one of event then it performs, and then again I have to wait to fire other event.

I'm currently facing an annoying problem that i can't seem to figure out. I have a gridview in my page, and i wanted to add a second header row to it. Well, i did that without any problems using the code below.
No problems so far. I then intended to add some filter to my gridview and so added a dropdown list in this second header i had created.
I simply added the control i previously had to my cell of the header.
[Code]....
The problem is that now, the SelectedValueChanged event is not firing when i change the value on my dropdown list. If i place her out of the gridview, the event fires normally, when placed inside the gridview the event apparently stops firing.
I have tried this with and without AutoPostback ON, though the final goal would be to have that option on OFF. (The postback would be caused by some other button on the same second header row, allowing the user to combine multiple filters simultaneosly)
