When I click the button image residing in footer template i just posts back and don't go to the itemcommand event.
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.
i wrote the following code to perfrom the inline deletion of datagrid elements.

This gets called when I go into Insert mode just fine, but it also gets called when I click the INSERT button to insert my record. I am trying to use this function to set default values for those controls on the form.
How do I stop this from being fired twice, or is there another method of setting the defualt calues?
The <ItemTemplate> loads properly, and the line:
<asp:LinkButton ID="generalcomments" OnClick="SetPage_N_of_All" runat="server" PostBackUrl=<%#DataBinder.Eval(Container.DataItem, "Filename")%>> <%#DataBinder.Eval(Container.DataItem, "Title")%></asp:LinkButton>
loads the page correctly, BUT it does not fire the onClick event (OnClick="SetPage_N_of_All").
The method SetPage_N_of_All is in the codebehind page and is as follows:
public void SetPage_N_of_All(object sender, EventArgs e)

ContentPlaceHolder mpContentPlaceHolder;
TextBox mpTextBox;
mpTextBox = (TextBox)this.Master.FindControl("page_N_of_All.Text");

I have a treeview control with Checkboxes, when 1 is checked/unchecked I would like to run some code, but for some reason nothing is being raised when I click on the checkbox. If this were a datagrid I'd be looking for the autopostback="true", but this control doesn't appear to have anything like that.

I have a problem with listview and I can't find any useful solution.
Here is my situation:
I have a listview with insert row and i need to do some calculations as user types in. Some fields are not filled by user but computed by javascript function (they are not inserted into db, they are shown for informational purposes only). These fields are just textboxes - computed ones are disabled. So i want to add some javascript functions to handle the computation, but i need this functions to have proper IDs. So i add them dynamically on listview.itemcreated with attributes.add. And that's where the problem begins.
If I use textbox.attributes.add("onblur", "some code"), suddenly all row commands of insert row stop working. They seem to cause a postback (all filled fields are blank after) but they are not firing any event. ItemCommand, ItemInserted, ItemInserting... Nothing. I have a masterpage and updatepanel in my website but i don't think that is the source of all problems. If I clear all javascript events from all textboxes and dropdownlists, row commands are working again. But I really need some client side computation and validation and I don't know how to make it work and still can insert rows.

rowdatabound event is not firing during postback ,What to do?First time pageload I am getting result as expected. When I click checkbox ,which is in grid ,my values which are in other columns get disappeared, that means during postback. How to maintain values in the grid even after postback.note : I did some small manupulation of data during rowdatabound event for the columns which are in the grid.
View 6 RepliesI have a checkbox inside the item template of a datalist, dtlLate. I want to detect the checkbox change and execute a stored procedure. When I click the checkbox a postback does occur but the dtl Late itemcommand doesn't fire. I am not rebinding the datalist on postback. I have tried with viewstate enabled and disabled. I have used Bold text for the dtlLate in the content page and in the codebehind to make it easy to find.

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]....
almost 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 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.
[code]...
And the code of my .aspx :
[Code]....
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.
