Forms Data Controls :: Dropdownlist Selectedindex Changed Will Not Fire ?
Jun 14, 2010I wanted to create a dropdownlist that would trigger an asynchronous postback and update the Gridview inside the Updatepanel. However, no matter what I do, when the dropdownlist changes, nothing in the UpdatePanel will change, even the TestLabel....I've been banging my head against the walls for days on this -- why won't this work? When I remove the UpdatePanel code and triggers, all the code works, eg, you change the dropdownlist andthen gridview updates -- but it refreshes the page and this is why I wanted to put the Gridview inside an Updatepanel to make it look cleaner.[Code]....
View 9 RepliesForms Data Controls :: Binding A Textbox To A Dropdownlist Selectedindex?
Feb 11, 2010I'm having trouble binding my textbox to my dropdownlist. I got it to work but I don't think it is the correct way of doing it. I have my DDL bound to a datasource and populating everything correctly. However, I couldn't find a better way of binding my textbox to it besides using the FormView control and its counterpart, Templates (edit,insert,etc) It looks messy and i was hoping there was a better way of doing it. I've researched it online for awhile now but I couldn't understand how to implement for my situation.
My DDL has company names in it and the datasource has all the information from the table including what I'm trying to have my textbox pull (Address).

Forms Data Controls :: Dropdownlist Pulls From Sql Source Into A Formview To Save To Another Table?
Feb 15, 2011I have a dropdownlist that pulls from a datasource. When a name is selected all information drops down to a formview. Once there 3 fields get populated from the dropdownlist and then there is 2 other fields that need user input. Once they hit submit, it should write to a different table in the same DB. I cannot get the fields to populate and write to the DB. Here is my code:

Forms Data Controls :: Prepare Dropdownlist Selectedvalue To Be A ControlParameter Source For ObjectDataSource?
Apr 12, 2010I have following in many controls:
<asp:ControlParameter Name="SvcCluster_Id" ControlID="frmConfigEdit$ddlCluster" PropertyName="SelectedValue" />
Everything was good before I bumped into the problem when declarative binding (SelectedValue='<# Bind("SvcCluster_Id") >') produced the error, because value has not been found in the list. So i moved binding to the code:
protected void frmConfigEdit_DataBound(Object sender, System.EventArgs e)
{
if (frmConfigEdit.CurrentMode == FormViewMode.Edit)
{
var svcCluster_id = DataBinder.Eval(frmConfigEdit.DataItem, "SvcCluster_id");
var ddlCluster = (DropDownList)frmConfigEdit.FindControl("ddlCluster");
if (svcCluster_id != null && ddlCluster.Items.FindByValue(svcCluster_id.ToString()) != null)
{
ddlCluster.SelectedValue = svcCluster_id.ToString();
}
}
}
But now seems like this happens later than ObjectDataSource tries to access frmConfigEdit$ddlCluster...
How to manage this?
I wouldn't like to move everything to the code (I mean creating Control parameters, etc)
p.s. Oops, actually it works ok for DataBound event! Sorry.

Forms Data Controls :: Can't Use The SelectedIndex To Identify The Access Row
Aug 18, 2010I display a GridView where ther user can choose a Datarow with the select action. I catch the selection with the "SelectedIndexChanged" event of the GridView.

My problem is I can't use the SelectedIndex to identify the Access Row because when the user uses paging/sorting the SelectedIndex is not the AccessRow. Somehow I have to identify the selected row the user chooses with the PrimaryKey in Access ("Number").
Forms Data Controls :: Using Gridview SelectedIndex In ControlParameter?
Mar 1, 2011I am having a problem with using A Gridview SectedIndex or value in a sql ControlParameter. When I select the row it does what I need it to except it shows that there is no data.
but if I add Default Value of 1 the data shows up, but it needs to read from the Gridview.

Forms Data Controls :: Selected Value In Gridview Not Accessible Via SelectedIndex
Sep 2, 2010I'm trying to keep these questions seperate for people searching after me, .
I have the following code on SelectedIndexChange of GridView1
[Code]....
I have a drop down list that you can choose values from, and depending on which item you pick GridView1 changes, this all works correctly, and if I select one of he rows the SelectedIndex changes. My problem occurs when you choose a different value from the drop down list, GridView1 Changes accordingly, and by default a record is selected. But selectedindexchange is never fired again until I manually select another record from the gridview which is a problem.

Forms Data Controls :: UpdatePanel Not Updating When The SelectedIndex Of The GridView Is Altered In The Code Behind
Mar 11, 2010I have a gridview in one UpdatePanel and a FormView in another UpdatePanel.
The FormView UpdatePanel refresh is triggered when the GridView SelectedIndexChanged event fires. This then displays the FormView. However when a user navigates to another page in the GridView or sorts the data then the GridView is refreshed and the SelectedIndex
is changed to nothing in the code behind via the GridView DataBinding event.
The FormView UpdatePanel does not refresh to reflect this. I have to manually set the FormView datasource to null and update the FormView UpdatePanel in the code behind.
My question is why doesn't my FormView UpdatePanel update when the SelectedIndex of the GridView is altered in the code behind.
