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?

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# - Buttons And ConfirmButtonExtender Added Dynamically?

Aug 11, 2010

I'm adding alot of buttons at runtime to my form. When i push these buttons i want a confirm window to pop up and ask if i'm sure to delete this item.How would i go by doing this.Every button is added dynamically so i expect that the confirmbuttonextender should also be added that way.Do i have to add a extender for each button or should i make one in the aspx file then change the targetID at runtime ?

div.CssClass = "BulletDiv";

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.

C# - Getting Dynamically Added Child Controls To Display In The UI

Dec 20, 2010

I am trying to create a RadioButtonListWithOther class that extends the RadoButtonList but I can't get the "Other" textbox to render on the page. When I step through while debugging I can see the control in the parent control's Controls collectio but it still doesn't render.

public class RadioButtonListWithOther : RadioButtonList
{
private TextBox _otherReason;
public RadioButtonListWithOther()
{
_otherReason = new TextBox();
_otherReason.TextMode = TextBoxMode.MultiLine;
_otherReason.Rows = 6;
_otherReason.Width = Unit.Pixel(300);
_otherReason.Visible = true;
}
protected override void CreateChildControls()
{
this.Controls.Add(_otherReason);
this.EnsureChildControls();
base.CreateChildControls();
}
protected override void OnSelectedIndexChanged(EventArgs e)
{
_otherReason.Enabled = false;
if (OtherSelected())
{
_otherReason.Enabled = true;
}
base.OnSelectedIndexChanged(e);
}
public override string Text
{
get
{
if (OtherSelected())
{
return _otherReason.Text;
}
return base.Text;
}
set
{
base.Text = value;
}
}
public override bool Visible
{
get
{
return base.Visible;
}
set
{
//Push visibility changes down to the children controls
foreach (Control control in this.Controls)
{
control.Visible = value;
}
base.Visible = value;
}
}
private bool OtherSelected()
{
if (this.SelectedItem.Text == "Other")
{
return true;
}
return false;
}
}

Here is my code to add an instance of this control to the WebForm:

protected override void CreateChildControls()
{
var whyMentorOptions = new Dictionary<string, string>();
whyMentorOptions.Add("Option 1", "1");
whyMentorOptions.Add("Option 2", "2");
whyMentorOptions.Add("Option 3", "3");
whyMentorOptions.Add("Other", "Other");
mentorWhy = new RadioButtonListWithOther
{
DataSource = whyMentorOptions
};
this.mentorWhy.DataTextField = "Key";
this.mentorWhy.DataValueField = "Value";
this.mentorWhy.DataBind();
Form.Controls.Add(mentorWhy);
base.CreateChildControls();
}
