Accessing the TextBoxes in a FormView from C# code behind

Question

User1618321365 posted

I'd like to set the values in the text boxes in a FormView when I am adding a new record to a database. I have attempted to use the New_Clicked event for the EditItemTemplate which gives me a procedure in the C#. However, I cant seem to find the TextBox objects that are on the EditItemTemplate from the C#. I see the FormView1 object and can get to FormView1.EditItemTemplate -- but then I can access the textBoxes.

 I see the construct "FormView.EditItemTemplate.EditItemTemplate.yyyTextBox" in the properties window for the TextBox -- but I cant access the TextBox from C# using this either ...

 

In the C# code I'd like to be able to express

...yyyTextBox.Text = "zzzzz";

and have this show up as the default in the TextBox.

To access child controls from their parent control, you need to use the FindControl method:

TextBox yyyTextBox = (TextBox)FormView1.FindControl("yyyTextBox");
yyyTextBox.Text = "zzzzz";

Now you have control of your TextBox and its properties and methods.

User1564875471 posted

you need to use Findcontrol function of the FormView to get a reference to its controls

try this :

 

     if (FormView1.CurrentMode == FormViewMode.Edit) 
       {
         TextBox yyyTextBox = (TextBox)FormView1.FindControl("yyyTextBox");
       
         // here you can access the yyyTextBox control
         yyyTextBox.Text = " any text";
       }
  

hope it helps

Try FormView.FindControl("txtBoxId")

Thanks for the excellent responses ... tried the suggestions and am getting closer. I inserted the code below. 

When I execute the page, I click the "New" link in the bottom of the "item" template from my FormView and using the debugger, I can look at the c# code results. If I leave off the if clause, the  yyyTextBox variable ends up with a null value (guess it cand frin the child control). If I add the if test, it doesnt pass -- so i guess ...

FormView1.CurrentMode != FormViewMode.Edit.

I cant seem to find how to get this situation to occur. Possible the FormView1.CurrentMode isnt changed to Edit status at the event iof clicking "New".

protected void NewButton_Click(object sender, EventArgs e)

{

if (FormView1.CurrentMode == FormViewMode.Edit)

{

TextBox yyyTextBox = (TextBox)FormView1.FindControl("DateTimeStampTextBox");yyyTextBox.Text = "02/10/2008";

}

}

you need to put that code in ModeChanging event instead ,

 

 protected void FormView1_ModeChanging(object sender, System.Web.UI.WebControls.FormViewModeEventArgs e)
 {
    
     // if the new mode is edit
     if (e.NewMode == FormViewMode.Edit) {
        //here you can access the controls inside EditItemTemplate
         TextBox yyyTextBox = FormView1.FindControl("DateTimeStampTextBox") as TextBox ;
         yyyTextBox.Text = "02/10/2008";
     }
    
     // if the new mode is insert
     else if (e.NewMode == FormViewMode.Insert) {
         //here you can access the controls inside InsertItemTemplate
         //Dim yyyTextBox As TextBox = FormView1.FindControl("DateTimeStampTextBox") as TextBox ;
         //yyyTextBox.Text = "02/10/2008"
     }
    
 }

 

Hope it helps

After investigating further --- I see the problem seems to be that there are two TextBoxes for each item in the formView -- one for the Edit Template and another for the Insert Template. When you use the findControl method, I need to describe which template i am referring to. thats what the if clause was doing -- picking out the right template. However, when I use the New_Clicked event, seems the FormViewMode hasnt changed to Edit at that time --- so I need a new event to trigger my C#??

Ahhh -- so close --- the following code was used for my codeBhind. Now I get through the tests for FormViewMode and execute the FindControl method. However, It doesnt seem to find the TextBox control. The value for yyyTextBox is returned NULL and the code halts -- telling me about the NUll value. I went into the properties of the TextBox for the Template and actually cut the value for "ID" and then pasted it into the C# expression -- so Im sure i didnt have a missspelling.

Thanks for your excellent and timely assistance. -- jim

 

protected void FormView1_ModeChanging(object sender, FormViewModeEventArgs e)

{

if (e.NewMode == FormViewMode.Edit)

{

TextBox yyyTextBox = FormView1.FindControl("DateTimeStampTextBox") as TextBox;yyyTextBox.Text = "02/10/2008";

}

if (e.NewMode == FormViewMode.Insert)

{

TextBox yyyTextBox = FormView1.FindControl("DateTimeStampTextBox") as TextBox;

yyyTextBox.Text = "02/10/2008";

}

}

User1618321365 posted

as another note -- i see from some other forums that the fact that I am using a masterpage may be an issue. I see some discussions regarding recursive usage of the FindControl() ... basically my simple test page places a formview onto the contentplaceholder of my testpage, sets up the sqldatasource to allow edit/delete/insert ... all works fine for the basic purpose. So my intent is to simply cause stuff determined in my C# codebehind to create data for any NEW entry to the database.

User1564875471 posted

 Jim, it seems that you need to use FormView  PreRender event instead of modeChanged ,

PreRender event fires later and so the Controls must be there in the Template, try  the following code :

 

 protected void FormView1_PreRender(object sender, System.EventArgs e)
 {
     // if the mode is Edit or Insert
     if (this.FormView1.CurrentMode == FormViewMode.Edit || this.FormView1.CurrentMode == FormViewMode.Insert) {
         TextBox yyyTextBox = FormView1.FindControl("NameTextBox");
         yyyTextBox.Text = "02/10/2008";
     }
 }

Thanks for the suggestion --- here's the code I used. had to add the "as TextBox" to instantiate the yyyTextBox variable. Went through this in the debugger and the mode tests worked fine as expected and all events seemed to fire at the right time. However, alas, the yyyTextBox variable still returns a NULL. I've read lots of the forums relating to this and it seems the control ID is still ambiguous even though my event is triggering on the correct template ..... thanks for your assistance!!

protected void FormView1_PreRender(object sender, System.EventArgs e)

// if the mode is Edit or Insert

if (this.FormView1.CurrentMode == FormViewMode.Edit || this.FormView1.CurrentMode == FormViewMode.Insert)

{

TextBox yyyTextBox = FormView1.FindControl("NameTextBox") as TextBox; yyyTextBox.Text = "02/10/2008";

I forget to change the TextBox Id  to "DateTimeStampTextBox"

 

try this code :

 

 protected void FormView1_PreRender(object sender, System.EventArgs e)
 {
     // if the mode is Edit or Insert
     if (this.FormView1.CurrentMode == FormViewMode.Edit || this.FormView1.CurrentMode == FormViewMode.Insert) {
         TextBox yyyTextBox = FormView1.FindControl("DateTimeStampTextBox") as TextBox;
         yyyTextBox.Text = "02/10/2008";
     }
 }

all works well and seems to provide a ton of functionality with minimal code of any kind -- just the few lines of C#. I was trivially able to insert a calender on the page and insert DateTime.Now.ToString() into the DateTimeStamp record ....

    Thanks again for the persistance.
