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'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 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've following gridview:
<asp:Panel ID="pnlScroll" runat="server" ScrollBars="Auto">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
[Code]...
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 a User Control that has been added to the page dynamically. When I click a button on that user control:
The button_click event is NOT being raised
The page posts back
The user control is removed from the page
Here's the button-click event on my User Control:
Protected Sub btnAddAttribute_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddAttribute.Click
Try
Dim attrName As String = txtAddAttributeName.Text
Dim attrValue As String = txtAddAttributeValue.Text
'ADD ATTRIBUTE TO ATTRIBUTE TABLE
putSQLData("INSERT INTO OD_Attribute_Values (AttributeName, AttributeValue) VALUES('" & attrValue & "', '" & attrName & "'")...........
I have a Gridview which contains templated column that has 5 checkboxes in it. When you click on one checkbox, I want to uncheck the other 4.
I am using the Item Template for this. I don't want the user to have to Select a row, before clicking on the checkboxes. Here is my non-working code to uncheck the other checkboxes. I realize it's not "SelectedRow" that I want since there's no selected row, so how do I find the row containing the checkbox that fired off CheckChanged?

I am unable to find any control in row editing event of gridview that i have put in edit template. I have to populate the dropdown control so that in editing the user can select value from the control.
How ever i can access the controls in row updating .But i need it in row editing event.
Here is the code.

I add one or more textbox controls to a repeater itemtemplate during OnItemDataBound.
The textbox controls are instantiated and then added to a placeholder.
My problem is getting the user entered values from those dynamically added textboxes. They do not seem to exist in the repeater items collection.

i want save the gridview in buttonsave event..
here i wrote the code like this
for (int i=0;i<gridview1.row.count;i++)
{
label lbl=(label)gridview1.rows[i].findcontrol("lbl");
Textbox txtname=(Textbox)gridview1.rows[i].findcontrol("txtname");
}
here i got the textbox value but am not getting label value how to get that label value..
I have a panel which has a repeater within it. Within the repeater I have a few controls. One of those controls is a Drop Down list which has an OnSelectedIndexChanged event. I can get this to fire without issue but I cannot find my DropDownList control within that repeater within the SelectedIndexChanged event . The repeater has an OnItemDataBound event and I can use the RepeaterItemEventArgs to find the control using e.Item.FindControl("ControlName") without issue but when that event occurs is NOT when I need to find the DropDownList.
What I want to do is have another control's Visible property be set to "true" when the value of the DropDownList meets a certain value. As far as I know I can only do this during the SelectedIndexChanged event and I can't change the signature of the event by trying to use RepeaterItemEventArgs.
I have a asp.net page where we need to dynamically generate a table, table row, and a checkbox controls in this row. A button serves Add Row and create checkbox function, which works fine. We have another button which serves on deleting the selected row if a user checks the checkbox. The deleting event is dynamically added to the checkbox. But the delete button is not working at all. I think that the page does not maintain the states of dynamically generated controls, even I set Page enable view state to True. Here is the code:
I am generating a table dynamically with one row having four cells.
First cell is having checkbox and below is the code how i declare it and assign it a new id at runtime.

I'm developing IP Blacklisting HttpModule in asp .net application and I found one very annoying thing. Each request to the asp net page generates tens of "subrequests" to application resources like images, client side scripts, styles etc.
Now in my application I'm listing to the BeginRequest event and when it is fired I'm loading Dictionary with blacklisted IPs from application cache and check user's IP against it. I've made a simple log of what is actualy happening during each page view, here are the results:
[Code]....
As you see, one request to Login page causes BeginRequest to fire 18 times, there is 18 dictionary loads, 18 lookups etc. That's not the way I want it to be.
Is there any other event that is raised only once per each request? Where do you place the blacklisting mechanism in your applications? I know I can do it through ISAPI filter, but the catch is, this site is on the shared hosting and I'm not sure I can use it on their IIS. Also I'm not sure if ISAPI filter can access some piece of cache with this blacklist (I don't want to load it from DB on each request, that's obvious).
I have gridview in my page that users can edit their data in gridview below is code:
<asp:GridView ID="GridView1" runat="server" CssClass="DGridView1"
AutoGenerateColumns = "false" Font-Names = "Tahoma"
Font-Size = "9pt"
HeaderStyle-BackColor = "#e0e0e0"
OnPageIndexChanging = "OnPaging" onrowediting="EditCustomer"
onrowupdating="UpdateCustomer" onrowcancelingedit="CancelEdit"
GridLines = "Both" OnRowDataBound = "OnRowDataBound" >
I define Lable in gridview that I want when users click on edit it show s some text in this lable so I wrote editcustomer metod like below:
protected void EditCustomer(object sender, GridViewEditEventArgs e) {
Label3.Text = "neda";
GridView1.EditIndex = e.NewEditIndex;
BindData();
BindData1();
}
But this error happen:
the name "lable3" doesn't exist in current context
I know because I define it in gridview it can't recognize but how I can solve it?
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();
}
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 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]....
but when i click the button on the grid, the alert comes up and if i select ok, i get the following exception:

This is driving me nuts, I cant figure out why the event OnClick doesn't fires when using a rewritten url (using URLRewritngNet).
Buttons lies everywhere on several pages and at the master page too.
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've a Gridview control using an ODS(ObjectDataSource) to fetch data. For the best performance and efficiency, I've turned-off the view state of Gridview (i.e. EnableViewstate = "false".And I've also enabled caching in the associated Objectdatasource. This eliminates as much as 50-60% performance optimization because it eliminates the DB round-trip .. courtesy ODS Caching.So, after this I got stuck into the famous "ODS sorting" issue but I managed to invent a tricky solution for it and its working fine
View 4 RepliesI have 5 infragistics webdatagrid controls on page, I am using paging and sorting features for the grids. For paging to work for a grid, I need to rebind the grid on every postback in Page_Init or Page_Load event and after that page_indexchanged event gets fired.
Now, when I click on any page number in second grid, I don't want data of other 4grids to be re-bind. I just want to know which grid has done postback and bind that particular grid.
I checked out Request.Forms["__eventargument"] but its value is comma (",").
Consider the scenario for asp.net gridviews and depending upon that I'll get idea to proceed with Infragistics controls.
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 10 RepliesWhen I click a server side control, such as linkbutton, I have to do something on Page_Init or Page_Load. How do I find the right LinkButton if I have many LinkButtons in this page. You know that Page_Init or Page_Load is execute before LinkButton_Click.
View 4 RepliesI am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
