Find HTML Control Using FindControl?

Apr 1, 2010

I add a select control to a ASPX page like below:

hgc = new HtmlGenericControl();
hgc.InnerHtml = @"<select runat='server' id='my_selectlist'>
<option value='volvo'>Volvo</option>
<option value='saab'>Saab</option>
<option value='mercedes'>Mercedes</option>
<option value='audi'>Audi</option>
</select>";

Then in a Button click event, I use the code below, try to get the value selected

HtmlSelect s = (HtmlSelect)hgc.FindControl("my_selectlist");
label.Text = s.Value;

I get a error:"Object reference not set to an instance of an object."Does anyone try it before?

How To Use The FindControl Function To Find A Dynamically Generated Control

Jun 10, 2010

I have a PlaceHolder control inside of a ListView that I am using to render controls from my code behind. The code below adds the controls:

TextBox tb = new TextBox();
tb.Text = quest.Value;
tb.ID = quest.ShortName.Replace(" ", "");
((PlaceHolder)e.Item.FindControl("ph_QuestionInput")).Controls.Add(tb);

I am using the following code to retrieve the values that have been entered into the TextBox:

foreach (ListViewDataItem di in lv_Questions.Items)
{
int QuestionId = Convert.ToInt32(((HiddenField)di.FindControl("hf_QuestionId")).Value);
Question quest = dc.Questions.Single(q => q.QuestionId == QuestionId);
TextBox tb = ((TextBox)di.FindControl(quest.ShortName.Replace(" ","")));
//tb is always null!
}

But it never finds the control. I've looked at the source code for the page and the control i want has the id:

ctl00_cphContentMiddle_lv_Questions_ctrl0_Numberofacres

For some reason when I look at the controls in the ListViewDataItem it has the ClientID:

ctl00_cphContentMiddle_lv_Questions_ctrl0_ctl00

Why would it be changing Numberofacres to ctl00? Is there any way to work around this?

UPDATE:

Just to clarify, I am databinding my ListView in the Page_Init event. I then create the controls in the ItemBound event for my ListView. But based on what @Womp and MSDN are saying the controls won't actually be created until after the Load event (which is after the Page_Init event) and therefore are not in ViewState? Does this sound correct?

If so am I just SOL when it comes to retrieving the values in my dynamic controls from my OnClick event?

UPDATE 2:

So i changed the code i had in my Page_Init event from:

protected void Page_Init(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
//databind lv_Questions
}
}

to:

protected void Page_Init(object sender, EventArgs e)
{
//databind lv_Questions
}

And it fixed my problem. Still a little confused as to why I want to databind regardless of whether it's a postback or not but the issue is resolved.

Using C# FindControl To Find User Control In The Master Page

Mar 31, 2010

So all I want to do is simply find a user control I load based on a drop down selection. I have the user control added but now I'm trying to find the control so I can access a couple properties off of it and I can't find the control for the life of me. I'm actually doing all of this in the master page and there is no code in the default.aspx page itself.

MasterPage.aspx

[Code]....

MasterPage.cs

protected void goToSelectedPage(object sender, System.EventArgs e)
{
temp1 ct = this.Page.Master.LoadControl("temp1.ascx") as temp1;
ct.ID = "TestMe";
this.UpdatePanel1.ContentTemplateContainer.Controls.Add(ct);
}
//This is where I CANNOT SEEM TO FIND THE CONTROL ////////////////////////////////////////
protected void lnkSave_Click(object sender, System.EventArgs e)
{
UpdatePanel teest = this.FindControl("UpdatePanel1") as UpdatePanel;
Control test2 = teest.ContentTemplateContainer.FindControl("ctl09") as Control;
temp1 test3 = test2.FindControl("TestMe") as temp1;
string maybe = test3.Col1TopTitle;
}

Here I don't understand what it's telling me. for "par" I get "ctl09" and I have no idea how I am supposed to find this control. temp1.ascx.cs

protected void Page_Load(object sender, EventArgs e)
{
string ppp = this.ID;
string par = this.Parent.ID;
}

Web Forms :: Using FindControl To Find Control Within A Table Cell?

Apr 20, 2010

Object reference not set to an instance of an object. when I try to access these dynamically created controls using FindControl.

I have a dynamically created control within a table cell. The table itself is contained within a page that has a master page. I've tried so many different ways to access this control.

Below is the latest iteration

AttrTable is the asp table, and row.Attr_Type is the name I've given to the control (it iterates through a datatable to set the names for the control)

tmpVal = CType(AttrTable.FindControl("TD_" & row.Attr_Type).FindControl(row.Attr_Type), DropDownList).Text
Below are various ways I've tried to access the control:
Dim form As Control = Page.Master.FindControl("form1")
Dim content1 = form.FindControl("ContentPlaceHolder1")

Web Forms :: Can't Find Textbox Using FindControl In A Dynamically Built Table

Feb 27, 2010

I have an asp:table control that I construct dynamically. I place a few textboxes in it within a for loop and assign their IDs in code. I'll include an abbreviated code fragment showing how I'm doing this:

[Code]....

The page then displays correctly and the ID is set correctly when I view the source, but when I try to access the textbox later when the form is submitted the call to FindControl(idStr) returns null no matter what I do.

Web Forms :: How To Find Out What HTML Does Each Server Control Renders

I try to run each control and then check what html did it render.

But this seems to me as an inaccurate method as whenever we add or remove the properties, or events of the control,the rendered HTML changes. Is there any book/tutorial/article to explain what is the standard HTML rendered by each asp.net control.

FindControl Getting Wrong Control In My Recursive Method?

Mar 11, 2011

I use the following method to find a control on an asp.net page recursively:

/// <summary>
/// Searches recursively for a server control with the specified id parameter.
/// </summary>[code]...

I hit a problem because it was returning the wrong control. I tracked the problem down to the standard FindControl method, and fixed it by checking that the id of the control returned did actually match the one requested like this:

foundControl = start.FindControl(id);
if (foundControl != null && foundControl.ID == id)
return foundControl;

My question is why does start.FindControl(id) ever return a control that does not match the id requested?

Panel.FindControl() Method Isn't Finding A Control That Has Been Added To It

Feb 9, 2011

Consider the following code, adding 2 textboxes with the same ID (oops):

protected void Page_Load(object sender, EventArgs e)
{
string TextBoxName = "TextBox1";
Panel p = new Panel();
TextBox t = new TextBox();
t.ID = TextBoxName;
p.Controls.Add(t);
if (p.FindControl(TextBoxName) == null) // <-------*******
{
TextBox t2 = new TextBox();
t2.ID = TextBoxName;
p.Controls.Add(t2);
}
Page.Form.Controls.Add(p);
}

The code is designed to stop adding the same ID twice. However, the Panel.FindControl() method is not finding a control that was added in the previous line of code.

Am I using this in the wrong way?

I mean - sure - I could manually iterate through the controls in the next level, like:

string TextBoxName = "TextBox1";
Panel p = new Panel();
TextBox t = new TextBox();
t.ID = TextBoxName;
p.Controls.Add(t);
TextBox t2 = new TextBox();
t2.ID = TextBoxName;
bool duplicateFound = false;
foreach( Control c in p.Controls )
{
if(c.ID == TextBoxName)
{
duplicateFound = true;
break;
}
}
if( duplicateFound )
{
t2.ID = TextBoxName + "__0";
p.Controls.Add(t2);
}

But I don't understand why this isn't working, whereas Placeholder controls and UserControls work fine.

The reason I am using Panels is for CSS styling. body > div > input - but still - it isn't working.

Forms Data Controls :: Getting Databaound Control Using FindControl?

Mar 18, 2011

I have a form with a basic FormView control. The FormView is set to Edit mode by default with only two textboxes and one button. I am populating the FormView using a Datatable from the code behind generated from a SQL Stored Procedure.

The data fills the FormView just fine. I am attempting to update the data using a SQL Stored Procedure by getting the values from the textboxes in the FormView on button click Everything seems to work and I recieve no errors, however the values I type into the textboxes is not passed to the stored procedure so eventhough there are no errors the data is not updated.

I know that the issue is not my stored procedure becasue if I use static values for the parameters in the code behind, the values are updated by the stored procedure.

I placed two plain textboxes and a button on the ASPX form and create a button click event for that button using the same code I use for the butten click event in the formview. When I add values to the non-databound textboxes, the data is updated correctly.

The question is, why can I not get the updated/changed values from textboxes in the FormView control?

Here is my ASPX code:
