Forms Data Controls :: DropDownList1.SelectedIndexChange Is Not Getting Fire From Pagertemplate..in Gridview?
Jan 14, 2010
I am problem with gridview pager template,i have a dropdownlist in my pagercontrol butdl.selectedindexchange is not getting fired up if i am trying to bind gridview at code behind.But if iam using sqldatasource instead its working fine.
I have a gridview which i would like to design my own paging. i already have the first, next, previous, last linkbuttons and they work perfectly.But i need to show the total amount of records that are in the gridview (ie. Not total amount of records on each page of the gridview but all records on all the pages). I have set my gridview to display 5 records at a time.I need something like Pages 1 of 10 , Total number of records returned is 50 , Records 5 of 50. Can this be done?Also how do i make the index of the first page of the gridview = 1 instead of 0
Might be easier just to show the code, then explain what's happening:
[Code]....
When I click either the pager buttons, the ProgressPanel displays, but the grid is not updated. However when I click the pager button again, the ProgressPanel is not displayed, but the grid data is updated. Below is my page code behind:
I have a Gridview that provides the user the student name for a particular class, a dropdown list to enter grades. If a grade of 'U' is given, a textbox appears in which the last day of attendance must be listed.
It works... though not as conviently as it could; the faculty would like to be able to tab from one dropdownlist to next in succession.
On each ddlGrades changes I write the value to the database and if a 'U' was chosen, display the textBox... but I can't figure how to set focus on the next ddlGrades control, or even the same ddlGrades control that initiated the postbock.
Below is my simplified .aspx followed by the codebehind
I have the following code for my radiobutton selectedindexchange, i have a hidden field in the gridview with the cid( which is the unique id for the records, the last column in the gridview is the radiobutton and i want to update my record with the value of that radiobutton.
its possible to use a DropDownList within the PagerTemplate to navigate to a specific record? I have been able to place the DropDownList outside of the FormView and PagerTemplate and make it work, however, I can't get it to work inside the PagerTemplate.
I am doing custom paging.I am adding my own LinkButton in the PagerTemplate. When I click the LinkButton it has to fire the GridView1_PageIndexChanging. How to do?
User double clicks on a grid and a new Window Opens...User enters information and then I am going back and updating parts of the record.Once the code comes back from client-side onDblClick I am expecting the SelectedIndexChanged method to fire (so I can do additional server side processing) but it doesn't. Is there something I am missing?Right now my onDblClick event looks as followed:
In a gridview i am having two dropdownlist.in page load first dropdown will be populated and when an item is selected with in that based on dat selection i need to bind second drop down list.My problem is that selectedindexchaged event is not firing for first dropdown.The codings i used is below
I've tried many different ways to try to get the selectedIndexChange to work for my dropdownlist. It doesn't seem to work, when I debug, I can see that the page is doing a PostBack but the method that suppose to be taking care of the select index change doesn't seems to be fired. I notice that there is no "handles" in many post so I was just wondering why it doesn't have it?On postBack I didn't rebuild the list so the selectedIndexChange value shouldn't reset to 0.Sub ddlAccess_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) ''handles ......?" ...
We use gridview for showing a data from table.It show fine in certain case like in table field dispostion is data and test but in table we put the string Ineligible Member/Member No Longer Enrolled - Spoke to Target and Wrong Number After Skip Tracing then it gives error. 'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.
The following is snippest my code ,tell me where i am wrong.
I've got a gridview which displays records from a table in SQL Server. Next I've got a details view which displays the details from the selected record. This works fine.
When the user selects a record, which then gets displayed in the details view, I'd like to make it possible for the user to edit the record. I've done searchs for this online, and found lots of responses, but none quite displaying an answer to the question I've got. I'm sure it is a simple thing I've done wrong, but at this point I don't know what it is I've done wrong. I've getting this error,"'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value".
I've got a SqlDataSource to display the data in the details view. And then I specified another SqlDataSource to use for the dropdownlist control in the details view. I converted the field, in the details view, to a template field and have been replacing it. Here's the SqlDataSource controls definitions:
i have a detailstview and sql datasource I am retrieveing the data so far no problems but afteradding a dropdownlist in edit mode and clicking edit button I get this error"
'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.
in my webpage gridview is there in that gridview gridTags_Updating event is there.when am keep a breakpoint inin that event will not fire as well as when am clicking update button gridview is disappear
Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DropDownList1.SelectedIndexChanged Response.Redirect("memberlogin.aspx?d=" + DropDownList1.SelectedValue.ToString) End Sub
but DropDownList1.SelectedValue.ToString expression returns the TEXT of the selectedItem.
I've got a GridView control with LinkButtons in different cells. Currently when someone clicks a link, it fires the ItemCommand passing the CommandName and the ID of the item the link is bound to. That all works fine. I need to modify it now to not use links anymore. It now needs to show a popup balloon with a link (styled to look like a button) and when the link is clicked, I want it to do the exact same thing. I'm sure there are several ways of doing this, but for time's and consistency's sake, I'm copying the method used from another page we have that is already doing this. It has a hidden DIV on the page with the link in it. When you hover over a link, javascript repositions the div and makes it visible.
So what I need to do is pass my CommandName and item ID to the javascript so that it can trigger the postback when they click that single link. I know this is not the only way to get to the end result, but what I want to do if possible, is still fire the GridView's ItemCommand and set he DataListCommandEventArgs' CommandName and CommandArgument properties. Can someone explain how, under normal circumstances, clicking the LinkButton in the GridView fires the ItemCommand? I know that the LinkButton's click event is forwarded to the GridView but what gets sent from the client side that let's the server know the link was clicked?
I have a gridview with a ButtonField. When I leave the button type as the default LinkButton, clicking that button fires the RowCommand and everything works as expected. As soon as I change the button type to ImageButton and assign an ImageUrl, clicking that button does not fire the RowCommand.
i have a grideview which their is a LinkButton control i want to wite some code in that event i i do that. I am providing the code for better understanding
I have a GridView attached to an ObjectDataSource (returning a DataTable) in a UserControl. The code is really simple. Data comes down fine when the page is first rendered. When I click on Select or Delete (inside TemplateFields), RowCommand is supposed to fire but it doesn't, the page goes straight to Page_Load. I literally have 0 other event handlers that are set on this control and everything else in the codebehind shouldn't even fire if it's a postback. Also on postback, the Select and Delete buttons disappear. It looks like the TemplateFields are still there but they're empty. The data fields (all of two columns) post back fine.
