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:


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 :: 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")

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(" ", "");

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:


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


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


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?


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


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.

Web Forms :: Adding Required Field Validator To Dynamically Built Table?

I have the following code, i add code for required validator, but when you make selection from dropdown to create the table, the page generates an error. Should the logic be somewhere else to add it to the table? i mean, dont they have to be there so when you submit the form, it fires the validation?

Line: 938

Using FindControl To Locate TextBox In Dynamically Created Template Field?

Jun 2, 2010

My problem is as follows. I have a custom GridView control where I generate the Template fields for each column. I'm using someone elses class that extends the Itemplate and returns lables for ItemTemplate, and TextBoxes for EditTemplate.

I need this in order to implement bulk edit for the gridview where users press button Edit and all fields become textboxes, they can then change the values, and click Update button at which point I need to be able to retrieve the values from the TextBoxes in these Template Fields.

What I have tried thus far: when user clicks Edit button, my dynamic code builds the columns and specifies that the Template field is an EditTemplate, it then adds these columns to the grid view. The gridview shows the textboxes with all values retrieved from sqldatasource.

When I press the Update button, the page does a postback, as I can see Page_Load event fire, I check for a flag that I previously set when the Edit button was pressed (I store it's value in View State) and call the Update method.

In it I iterate throught the gridview rows collection, check that the RowType of each row is DataRow and call GridView.UpdateRow(i, false), passing each rows index to the UpdateRow method.At this point I have tried everything I can to find the values stored in the textboxes, but I cannot find any of the textbox controls.

I've tried using the current row's FindControl method and specifying the name of the textbox field,I've tried using Request.Params method where I can tried passing the client id, as it seen in the View Source of the page such as this


Still no luck, I've tried going up an down the Row's cells, controls collections, it seem to list the counts for rows correctly, the same goes for the amount of cells for each row, but at no point was I able to actually locate any controls such as textboxes or anything else and retrieve any values from them.

Web Forms :: Event Handlers For Dynamically Built Controls?

Mar 22, 2010

reading on the forums about assigning event handlers to controls that are dynamically created via code and am just not getting anywhere.In my particular case, I'm rolling through a directory of images and creating ImageButton controls on the fly and want to assign the OnCommand event to a single handler.Then, by using the CommandName (which is different for each control) I can figure out which ImageButton was clicked and act accordingly.

The snippet below (which can be found in many posts on this topic) is inside a foreach which loops through the directory and gets each FileInfo (fi).Each is then added to a PlaceHolder (phImages).


This code compiles and runs but the event handler is never invoked when an ImageButton is clicked. I believe this is because you cannot, without some coding I'm not familiar enough to do yet, assign a handler to multiple controls.I say this because I ran into a similar problem in a Silverlight app I wrote and had to use a lambda (=>) operator to do something similar (although I admit to not knowing enough about this to know if this situation is the same).

Web Forms :: Line Breaks In Dynamically Built Placeholder Control?

Feb 17, 2010

I have a Placeholder control on Employee Main Menu. Several SQL Data sources are run at page load in order to notify employees that something is due. Each "something is due" message is loaded into a unique label. Therefore the Placeholder could have several labels in them. For clarity's sake I'd like them separated by line breaks. However I understand from reading a previous forum item that "< /br>" are ignored. How can I embed a line break when PlaceHolder_Msg.Controls.Count > 1

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.




protected void goToSelectedPage(object sender, System.EventArgs e)
temp1 ct = this.Page.Master.LoadControl("temp1.ascx") as temp1;
ct.ID = "TestMe";
//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;

Forms Data Controls :: Create An Instance Of A TextBox In A GridView When Using FindControl?

Dec 28, 2010

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>?

<form id="form1" runat="server">
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">

DataSource Controls :: Enabling Paging On ObjectDataSource That Is Built Dynamically In Code Behind?

Oct 28, 2010

I have the following on my aspx page


Then in my code behind i have the following set up in 4+ button events, since each button serves a different purpose.. Prior to this past week, i was only working with 2 gridviews on the page.. that were linked to this datasource.. so everything was fine.. but recently had to add a Datalist to display the results a certain way.. I got it all working, but now that more records are in the table the datalist is growing in length on the page and cant figure out how to modify the current code to enable paging without having to redesign the logic all together to get it enabled.

Based on what i have below and above, is there a solution i can implement to implement paging ONLY for the Datalist? Or if it cant be specific, if enabled, will it affect the gridview that is already configured to enable paging, which already works?

Master Page Basically Contains A Menu Built Using HTML Table

Feb 13, 2012

I have a situation where I'm using a single Masterpage and two Content Pages. The Master page basically contains a menu built using an HTML Table. The one Content Page contains the marjority of my site content. The way the menu works is that when user selects a menu item, a javascript function executes that evaulates which menu item was selected.

Now, this is where I'm not sure what to do next. Should I load the next Content Page in this javascript function or somewhere in the CodeBehind of the Content Page? I'm trying to find examples where I can load a page using Javascript but not having any luck.
