How to handle page indexing , editing and cancelling events in asp.net?
View 2 Repliesalmost done with my gridview model... Everything is working fine, bit today I noticed that my gridview delete only works on the first page of the paginated gridview. As soon as I goto the next page of my (eg) 10 rows, I can click on delete what I wan't but nothing happens. So this is what i use:
I have a gridview with a datasource, including filter- and selectparameters, paging, ipp selector etc. No code behind used.
For the delete of a row I use a imagebutton in an templatefield:
<asp:TemplateField>
<ItemTemplate>
<asp:ImageButton SkinID="ImageDelete" runat="server" ID="ImageDelete" CommandName="Delete" OnClientClick="event.cancelBubble=true; return confirm('are you sure?');" />
</ItemTemplate>
</asp:TemplateField>
In my SQLdatasource I use a Deletecommand and deleteparamter:
DeleteCommand = "DELETE FROM [TblMessages] WHERE IDtblmessages = @IDtblmessages"
<DeleteParameters>
<asp:Parameter Name="IDtblmessages" Type="Int32" />
</DeleteParameters>
it's working fine on the first page, but not on a nother page when I'm paging throught the total set.
I also use a filterexpression and selectparameters (bases on dropdownlists) to filter the gridview. This also works great, but the same ater applying a filter: the delete imagebutton doesn't work then.Just found out it's caused because something I completely forgot: the gridview resides in a updatepanel. My structure is as follows:
masterpage > content > updatepanel > gridview
I have as asp.net website the code behind is C#.
i my application Page load method is firing two time.
I know you can do paging in gridview but is there a way which allows u to load one page ie page 1 and then when the user select page 2 it loads that page...because I will have 100,000 rows and I dont want to load all of them.. But I need to show all, so is there a way which u can do paging which allows u to load a page at a time?

View 1 RepliesI have a gridview on my page. I have a checkbox in each row of this gridview. For each checkbox in the gridview, I'd like to update my table accordingly, but I don't want them to have to hit a submit button every time they check the checkbox. I want them to check all the boxes they need to and at the end, they should hit one submit button.
View 12 Replies 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 couple of [WebMethods] in my code behind and using jquery ajax to get data from server. And then it happens :). After some time while page is inactive when i try to click on button which should have send request to server it simply does nothing for about half of minute and only then event is fired and i get response from server.
my javascript looks something like this:
[code]....
I had implemented the Ajax timer control to update Gridview data(along with Progress bar inside Gridview) after some interval of time.Below is the full code:
HMTL:
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
<%--style & Script for progress bar in Gridview --%>
<script type="text/javascript" src="//code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript" src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
<link href="css/jquery-ui.css" rel="stylesheet" />
[Code] ....
C#:
protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack) {
BindGrid();
} }
protected void BindGrid() {
string query = "SELECT * FROM Table";
[Code] ....
It is working fine except that the Gridview paging is taking some time(15-20 seconds) to go to next page.
I cant for the life of me get the PageIndexChanging event to fire. Please advice.

I've put a simple gridview on my Asp.net webpage. I've configured the fields via C# code:
gvMainDataGrid.AutoGenerateColumns = false;
gvMainDataGrid.AutoGenerateDeleteButton = false;
BoundField bfldSeqNmbr = new BoundField();
bfldSeqNmbr.DataField = "PKSequenceNmbr";
bfldSeqNmbr.Visible = false;
gvMainDataGrid.Columns.Add(bfldSeqNmbr);
BoundField bfldEmployeeCode = new BoundField();
bfldEmployeeCode.DataField = "Employee Code";
bfldEmployeeCode.HeaderText = "Employee Code";
gvMainDataGrid.Columns.Add(bfldEmployeeCode);
BoundField bfldProjectCode = new BoundField();
bfldProjectCode.DataField = "Project Code";
bfldProjectCode.HeaderText = "Project Code";
gvMainDataGrid.Columns.Add(bfldProjectCode);
BoundField bfldProcessCode = new BoundField();
bfldProcessCode.DataField = "Process Code";
bfldProcessCode.HeaderText = "Process Code";
gvMainDataGrid.Columns.Add(bfldProcessCode);
BoundField bfldActivityDate = new BoundField();
bfldActivityDate.DataField = "Date";
bfldActivityDate.HeaderText = "Date";
gvMainDataGrid.Columns.Add(bfldActivityDate);
BoundField bfldActivityHours = new BoundField();
bfldActivityHours.DataField = "Activity Hours";
bfldActivityHours.HeaderText = "Activity Hours";
gvMainDataGrid.Columns.Add(bfldActivityHours);
CommandField cfldDeleteButton = new CommandField();
cfldDeleteButton.ShowDeleteButton = true;
gvMainDataGrid.Columns.Add(cfldDeleteButton);
It's data source is a Dataset retrieved from a webservice. Here is the C#code to bind the data to the gridview
Service1 MyService = new Service1();
dsMainData = MyService.GetData(strIdNumber);
gvMainDataGrid.DataSource = dsMainData;
gvMainDataGrid.DataBind();
It retrieves great. No problems at all. Then, when I actually try to use the delete button, I get an error that the RowDeleting event is not being handled. I thought that was pretty explicit, so I created the event:
private void gvMainDataGrid_RowDeleting(Object sender, GridViewDeletedEventArgs e)
{
return;
}
Well.....that didn't work. So, I thought that maybe I needed to configure it via the actual aspx file. So, I changed
<asp:GridView ID="gvMainDataGrid" runat="server">
</asp:GridView>
to this:
<asp:GridView ID="gvMainDataGrid" runat="server" ondeleting="gvMainDataGrid_RowDeleting">
</asp:GridView>
But, no avail. I've scoured the web and tried so many combinations of capital letters and whatnot -- but no effect.
protected void grdMain_RowDataBound(object sender, GridViewRowEventArgs e)
{
}
<asp:GridView ID="grdMain"
runat="server"
OnRowDataBound="grdMain_RowDataBound"
I have a gridview,sqldatasource and a link button for delete in the sample code below
When Delete is click the confirmation pops up. When I confirm yes, the rowdeleting event doesn't seem to be firing. I addeed a label to see if the event is firing. To avoid runtime errors I added a dummy but actual sql delete command. Once If I get it to work, I want call a stored procedure to delete the row.
My question is
1. Why is the gridview row deleting event not fired.
[Code]....
I have a very simple page that consisist of an UpdatePanel that contains a gridview. The gridview includes a delete button for each row, which should fire the Delete event. But the event never fires. If I set a breakpoint inside the event handler, it never gets hit and the row does not get deleted. When I say OK on the confirm dialog it just goes back to the page. I tried taking out the confirm button extender
ASPX:[Code]....
i am using gridview for data manipulation. in gridview i have added a Edit and a delete button as a template field like
<asp:TemplateField HeaderText="Edit">
I'm trying to fire the RowCommand event on a DataGrid control. I've previously done that, but not in this precise case.
Actually I'm working on someone else code so I can't really change the structure of his page excepted if it's really necessary.
The code of the page is heavy, so I've summarized the problem in a small project and the page behaves the same way too.
Basically I have a GridView which I bind to a DataSet. According to those data, I sometimes need to add, at the end of a row, a "Details" button (a LinkButton).
By pushing this button, I want to show a second GridView containing those details.
Let's add to this that the columns number of the first GridView is variable, those LinkButton need to be added dynamically.
The first GridView is generated without any problem and when my mouse is over one of the LinkButton, I can see that the link is something like "javascript:__doPostBack('dataGridView$ctl02$lnkDetail','')". When I click on this link and debug step by step : Page_Init, Page_Load, OnPrerender, RowDataBound but no RowCommand, and I don't know why!
In the exemple, I've explicitly set the EnableViewState to true from what I've read here and there, but nothing's changed.

View 7 RepliesIn a .Net 2.0 project, I have a Calendar control within a GridView that has a method set for its OnSelectionChanged event. However, the event never fires and I don't understand why. Here's what's in my aspx page:
[Code]....
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.
View 4 RepliesI have done this successfully in another project and seemingly copied the code from it to a new one, yet it doesn't work.
I have a custom gridView with the following code:
<asp:GridView ID="gvCustomEditors" runat="server" AutoGenerateColumns="False"
I've been reading up on the problems with dynamically created controls and how they have been solved. The posts I have come across are creating the controls in a panel or some other open place. I can't seem to get my checkbox to fire the event from inside a gridview. below is the code behind from inside the GridView PreRender event.
[Code]....
..And the Checked Event..
[Code]....
So after all this, nothing happens. I get the postback flash but my command inside the checked event doesn't fire.I tried putting the dynamic creation of the checkbox in Page Load with no effect.. I think because I can't place the checkbox inside the GridView under page load.
i am using link button inside my gridview .
it is firing in IE but not working in mozilla.
