VS 2008 Dynamically Added Gridview Row Not Being Detected

Jul 27, 2011

I'm adding a row to my gridview like this in the RowDataBound event

Code:
If (Not isDisbursementRowAdded) Then
Dim row As GridViewRow
Dim cell As TableCell
row = New GridViewRow(e.Row.RowIndex + 1, e.Row.RowIndex + 1, DataControlRowType.DataRow, DataControlRowState.Normal)

[code]...

I've looked at the tables tr and td elements and they all have opening and closing tags.

Forms Data Controls :: Child Gridview Editing On Dynamically Added Nested Gridview

Jan 3, 2010

I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.

OnRowEditing="grdChildGridEdit_RowEditing"

The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).

I was trying to trigger it throughuse the registering the event:

Forms Data Controls :: Access Dynamically Added DropDownList In GridView?

May 18, 2010

I'm dynamically adding a DropDownList to the GridView in edit mode and I have set the TextBox Visibility to False. In edit mode I can see the DropDownList and I'm able to select an Item from the DropDownList but not able to access the SelectedValue in RowUpdating Event. How to get the selectedvalue of this DropDownList?

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow And (e.Row.RowState And DataControlRowState.Edit) > 0 Then
Dim ddl as DropDownList
FillStateList(ddl)
e.Row.Cells(4).Controls.Add(ddl)

ddl is the DropDownList that is added dynamically. And the default Textbox that is in the Edit mode is set to invisible. So there are actually two controls in the same cell in edit mode(TextBox is invisible).

DirectCast(Gridview1.Rows(e.RowIndex).FindControl("ddl"),DropDownList).SelectedValue

If I use the above statement I'm getting NullException.This is Probably because its a BoundField. Is there a way I can access the DropDownList 'ddl' SelectedValue?

State Management :: How To Make An Image Control (dynamically Added To A GridView Column In It's RowDataBound Event)

Mar 28, 2010

I have a gridview that on it's RowDataBound event I dynamically add Image Controls to some columns.

The problem is that I lose these images on the next PostBack.

OBS: The GridView's EnableViewState propertie is already set to true

I know about the page lifecycle, but how can I persist these images if I have to add them on the RowDataBound event?

In addittion, if I add a static TemplateColumn with an Image Control and I set it's ImageUrl propertie inside the RowDataBound event it will obviously persist between postbacks. The problem is that I don't know how many columns with images I'll have, it's defined on the datasource.

VS 2008 Adding Columns To A Gridview Dynamically

Jul 13, 2010

I have seen code for adding columns at runtime but here is another scenario for you. I am using a SQLDatasource control for my gridview. And the data returned can have different columns based on the filter meaning one time I may have a column A1, A2, A3 and another time I may have A2, A3, A4. Is there any way I can look at the columns when it is binded at the beginning and add the columns first?

I really need to use the SQLDatasource though because I am connecting to an AS400 and it is using a connection already made in the webconfig and do not know any other way. I do if it was MSSQL server but not this.

VS 2008 Datakey - Adding Row Dynamically To Gridview

Jul 27, 2011

I have a situation where I needed to add a row to my gridview. So say I have rows 3, 4 and 5.

My Datakeys are defined as "ID, CostingID". I did that so I can reference the two ID values I need when saving records.

here is the code in my RowDataBound event.

Basically if it is a datarow, I'm adding the value dataitems so I can get a sub total in the footer row.

Then, I have a boolean field called isDisbursement. So I sort my data by that field. So all records with the disbursement flag as true will display first.

Then as soon as the disbursement flag hits false I add a row to display the Total of the disbursement records value field.

All this works. My problem is, because I added a row at index 4 it inherits the datakey of the row that was at index 4 before. So when I'm looping through the grid rows to save the values I'm having a problem. I've attached an image so you will understand better what I'm trying to achieve. The "Total Disbursements" is the row I added. But it gets the following rows datakey because it is now at index 4.

when I do this, as soon as I reach row 4, although it doesn't have a CostingID it gets the CostingID of row 5 that used to be row 4:

Code:
Dim CostingID As Long = Convert.ToInt64(Me.grvCostings.DataKeys(row.RowIndex).Values("CostingID").ToString)
Dim strValue As String = CType(row.FindControl("txtValue"), TextBox).Text

Code:
If e.Row.RowType = DataControlRowType.DataRow Then
If Not IsDBNull(DataBinder.Eval(e.Row.DataItem, "value")) Then
_SubTotal += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, _
"value"))
End If

Cannot Find Selected Value Of Dynamically Added Controls In Repeater / How To Dynamically Add The Controls

Jan 11, 2011

I am creating a survey page that has a list of questions and answers that can be radiobuttonlists, checkboxlists or textboxes. These controls are added dynamically to a Repeater in its ItemDataBound event using Controls.Add.

I've managed to render the page ok but when I submit the form and iterate over the controls in the repeater to get the selectedvalues of the radiobuttons and textbox values, FindControl returns null. What do I need to do to get get the selected values? I've tried iterating over the RepeaterItems but that returned null too. I've tried different types of FindControl but it never resolves the control types.

It works if I add a declarative DataBinder in the Repeater like this

<asp:Repeater ID="rptSurvey" runat="server" Visible="true" EnableViewState="true" >
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "Question") %>
</ItemTemplate>
</asp:Repeater>

However, I want want to dynamically add the controls but in doing this i cant get the selectedvalues when submitting. This is tha main structure of my code...

C# - Controls Added Dynamically Not Visible From The Code Behind?

Jul 7, 2010

I'm adding a dynamically built set of checkboxes to an asp.net page from the code behind with something like this in a recursive fashion:

pnlPageAccessList.Controls.Add(myCheckboxControl);

The controls show up fine on the page, but they don't show up when I view source, nor can I access them from the code behind.If I add the controls in the on_init method, they work. But I have some business rules driving changes to the list of controls itself that require I fire the add method elsewhere. Has anyone seen this before? I'm away from work so I can't copy the exact code.

I have two terrible ideas for how to get it working. One involves some jQuery and a set of hidden controls holding a big array of integers; the other is run the method on_init AND on my other events so the controls at least show up. Both smell like ugly hacks.
