This does NOT work. What's wrong here?How do I accomplish my goal? I MUST use the Button1_Click event for this one.

I want to create an accordion inside a gridview with the following functionality:
The user will only see one field of the gridview initially, the ProductCategoryID. When the page loads it will only query the ProductCategoryID and this will be the only field displayed.
Next when the user clicks on the accordion to expand it inside the gridview I would like to query the database to get all Products that are part of the ProductCategory. I will query using the ProductCategoryID that is being displayed.
I need to do this for performance issues. The main thing I am looking for is how to query the database once the user expands a given ProductCategoryID.
but now I think of it one thing I need to know: when you bind an accordion to a dataset will it create one pane for each record returned? It might be better to put the gridview inside the accordion. I'm willing to do either, as long as it works

View 1 RepliesI have a label control inside of repeater and I can't seem to get FindControl to locate the label inside of the repeater or even the repeater itself. I'm not sure what I'm doing wrong here. OnItemDataBound is firing because "hello1" is being written but if I put anything inside of the For Next loop of rptMarketFundamentals, nothing is run inside of it.
<asp:Repeater id="rptMarketFundmentals" runat="server" DataSourceID="dsMarketFundamentals" OnItemDataBound="rptMarketFundamentals_ItemDataBound">
<asp:Label ID="lblOwnershipCategory" runat="server" Text='<%# Eval("OwnershipCategory") %>' />
</asp:Repeater>
Sub rptMarketFundamentals_ItemDataBound(ByVal Sender As Object, ByVal e As RepeaterItemEventArgs)
Response.Write("hello1") 'this works
Dim dataItem As RepeaterItem
For Each dataItem In rptMarketFundmentals.Items
Response.Write("hello2") 'this does not work
Dim lblOwnershipCategory As Label = CType(dataItem.FindControl("lblOwnershipCategory"), Label)
If lblOwnershipCategory.Text.ToLower = "family firm" Then blOwnershipCategory.CssClass = "highlight"
End If
Next
End Sub
[Code]....and datalist works fine if its Stand Alone but not when used with Accordion...
View 8 RepliesI'm trying to build a website for real estate listing. now the data would look like a datagrid. and while clicking on it, it should open under the clicked row the dynamic data related to the specific row. (like an AJAX accordion). this website for example ( ignore the language, couldnt find any better example [URL] Now, i've been told that this works by using "Dynamic Div Creation" which i have no idea how it should work this way. Is it possible to make it work by using an Accordion inside a datagrid? or what?

Iwrite this code but I get
Object reference not set to an instance of an object.
I have a dynamic gridview in which i need to add textbox, checkbox, imgButton in the cell dynamically.
At the moment user click on the imbgutton, a click event fire and i need to capture the user input on the checkbox and textbox of the particular cell.
I have problem in finding out the checkbox and textbox control in the imgbutton click event. The cause is i do not know which row in the gridview i need to search to for the control.
I have try gridview.Fincontrol but fail.
using the GridView FindControl.
What I've done is I've setup a Gridview with a datasource to show only 1 of the columns I need from the datasource, but I also have another ItemTemplate Column in which I have a dropdownlist with another datasource that I've bound to the dropdownlist.
What I need to do is have the dropdownlist show the selected one when compared to a id from datasource in the gridview.
i have button field in grid view, basicly i want to show to in some of the row only, but i cant find the "ID" using find control
This is my aspx code

I generate dynamically an usercontrol, the user write the quantity, 3 or 4 or 5, press generate and get N controls to fill with cars parts.I need get the values inside any textboxes but the method find never found the controls...I am using this code to generate dynamically my controls:
[Code]....
when the controls is loaded into the WizardStep, I need to find it to get the values inserted by the user in the textboxes.
[Code]....
but I never find the control always is null, I place it inside a Panel called UnidadesPanel.
my HTML.
[Code]....
Can one use the findcontrol to access the row.cells value? (C#)

[/code]
I though that this would work, but alas no.
I have a gridview with several ItemTemplates. The first contains a checkbox the rest contain textboxes. I then added dynamically some bound controls like this:
BoundField bdfPrivName = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfPrivName, "PrivName", "Priv Name");
BoundField bdfDescription = new BoundField();
clsUtilities.SetBoundFieldLeft(ref bdfDescription, "PrivDesc", "Description");
BoundField bdfLive = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfLive, "Live","Active?");
grdExisting.Columns.Add(bdfPrivName);
grdExisting.Columns.Add(bdfDescription);
grdExisting.Columns.Add(bdfLive);
I then use FindControl to locate the checkbox and textboxes and perform my logic based the result
foreach (GridViewRow gvr in grdMissing.Rows) {
mckbAny = (CheckBox)gvr.FindControl("ckbAdd");
mtxtApplyDate = (TextBox)gvr.FindControl("txtAddApplyDate");
mtxtDateToAdd = (TextBox)gvr.FindControl("txtAddDateToAdd");
mtxtDateToRemove = (TextBox)gvr.FindControl("txtAddDateToRemove");
etc.
This all worked fine. I then got a request to put the bound fields as the second, third and fourth columns, after the check box and before the textboxes. I found that this was easy to do by changing the Add's to Inserts as follows:
grdExisting.Columns.Insert(1, bdfPrivName);
grdExisting.Columns.Insert(2, bdfDescription);
grdExisting.Columns.Insert(3, bdfLive);
It looked fine of the page, but the FindControls, all of them fail to work.
Label1.text = CType(GridView_MyAds.FindControl("ItemId")
I need this correctly done....
I have a dropdownlist embedded into an asp.net gridview. I have successfully populated the dropdown list in the footer but have not been able to populate the dropdownlist in the EditItemTemplate. Here is my code that works. I need to do the exact same thing for a dropdownlist embedded in the update functionality of the gridview.

I have bootstrap accordion and it is inside repeater,
<asp:Repeater ID="Repeater1" runat="server" >
<ItemTemplate>
Employee Name: <ul><%# Eval("Name") %></ul>
[Code]....
There is one employee, so the first two accordions is working fine from toggle up and toggle down
SCENARION 2:
There are 3 employees, for the first employee the first two accordions is working, but the rest are not.
So the problem here is when I click the accordion of second employee it does not toggle down but the first employee's accordion is going down.
What I want here is each employee can toggle down and toggle up their own accordions, even though that accordion don't have data.
In my Application, I am using User control which contains one GridView and few Buttons. GridView Contains CheckBox in Item Template of first Column for Selection purpose. Now on one of the Button's click Event I am traversing through the GridView and find which row is selected.
Following is my Code for traversing which is not working:
foreach (GridViewRow row in gvCallSheet.Rows)
In my GridView I use FindControl/<FooterTemplate> with a TextBox that you can enter an integer with a comma
into the TextBox, because I create an instance of the Textbox first and then remove the comma out of the integer before the TextBox is used to update the table in the database.
However once the data is in the table and displayed in the GridView if you try to change the integer and use a comma in the GridView you cannot because FindControl/<EditItemTemplate> will not create an instance for you to remove the comma from the integer before it updates the table because FindControl/<EditItemTemplate> doesn't allow you to create an instance of the TextBox first, instead when you try to use the instance that looks like was created it gives an error stating:
Object reference not set to an instance of an object.
So the question is:
HOw do you create an instance of a TextBox in a GridView when using FindControl/<EditItemTemplate>?

I've got a gridview with a few textboxes in each row which I want to insert into a database, after a user clicks a submit button (thats outside of the gridview)
This is my code for the gridview
[Code]....
And this is my code for the button
[Code]....
But when I click the button it gives me this error
"Multiple controls with the same ID 'Label12' were found. FindControl requires that controls have unique IDs."
How do I give the controls unique IDs if they are in a gridview and the rows are database driven?
I have this...

I'm doing this in my Master Page. I want to access a Linkbutton within the Gridview and set the enabled = false; I tested this and it works all the way up to the first if statement.If I insert a response.write to get the frmctrl.ID, I get all of the controls on the page. BUT, can't get the controls within the gridview.How do I get the contorls within the gridview? I prefer not to do this using Findcontorls and esp setting the control to Public.

My GridView uses auto generate Edit & Delete command button. And then program the insert button. I want to do something when users click the Edit button so I wrote something like this:

And next is my code....

So basically what happens is, the accordion is populated by a dataset and in turn the gridview is then supposed to populate with data depending on the hidCusType from the parent pane of the accordion.
But I get the following error...
The name 'AccordionItemType' does not exist in the current context on this line...
