Hey,
u have mistaken..
Not here..
In Javascript write function...
Call only a single function from codebehind...
But make difference in Javascript...
Got it ? 
Thanks,

To get something you must have to try once.

Hi,
I have an appln where in i need to create, text boxes and drop downlists dynamically, the issue here is, how do i retreive the text stored in text box and value selected in the combo.
Thanks in advance
|

Just like you normally would. Creating the controls dynamically doesn't change how you access the properties.

but i am unable to refer to the text property for textboxes,
here is how my code goes, to create control
Dim fldMetadata As TextBox
fldMetadata = New TextBox
fldMetadata.ID = "txtID"
Panel1.Controls.Add(fldMetadata)
I refer to the controls like this,
Dim ctrl As Control
For Each ctrl In Panel1.Controls
If ctrl.ID Like "txtID" Then
'Here i should be able to refer to the control's text property
End If
Next
thanks

You then should be able to do ctrl.Text=".... "

Not really. I just tried it and works fine here.

I think I miss something. But I am unable to get Text property for Control instance as you told.

I made a mistake by doing a winform and not a webform  You can get it in a winform but not webform.

If ctrl.ID Like "txtID" Then
'Here i should be able to refer to the control's text property
TextBox txt = (TextBox)ctrl;
Now use txt for getting the textbox properties.

Adding to Paul's post, are you getting some problem when retrieving value ? If you are not getting the value entered, check the event where you create dynamic controls. It should be before ASP.NET loads the viestate. Init would be appropriate for dynamic controls.
|
|
|
|
|
Yes, i am unable to retreive the value entered, Pls can you be more clear, with the last post, i am unable to understand,
|
|
|
|
|
This is a viewstate issue. Hope you know about viewstates. It's mechanism used to keep data across postbacks. For solving the problem, override oninit event and add your controls over there. Then ASP.NET will maintain viewstate for the control and you can get it from Controls collection.

Hi
You are dynamically created textbox like this.
Dim fldMetadata As TextBox<br />
fldMetadata = New TextBox<br />
fldMetadata.ID = "txtID"<br />
Panel1.Controls.Add(fldMetadata)<br />
There should be number of text box.
When u creating the control dynamically the u cannot specify same id
to all control. u have assign unique id to all textbox in page which u
create dynamically.
R u creating control dynamically in for loop?
Can u paste code here?
Regards.

I create two textboxes and dropdownlist on page load event.
I have one Button and one placeholder on the page.
On page load event,add all dynamically created in place holder and on button click event, I get values of the textboxes and selected value of dropdownlist.
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
CreateControls(); <br />
}<br />
public void CreateControls()<br />
{<br />
TextBox MyTxt1=new TextBox();<br />
MyTxt1.ID = "MyTxt1";<br />
TextBox MyTxt2 = new TextBox();<br />
MyTxt2.ID = "MyTxt2";<br />
DropDownList MyDDL1 = new DropDownList();<br />
MyDDL1.ID = "MyDDL1";<br />
MyDDL1.Items.Add(new ListItem("1", "1"));<br />
MyDDL1.Items.Add(new ListItem("2", "2"));<br />
DropDownList MyDDL2 = new DropDownList();<br />
MyDDL2.ID = "MyDDL2";<br />
MyDDL2.Items.Add(new ListItem("1", "1"));<br />
MyDDL2.Items.Add(new ListItem("2", "2"));<br />
<br />
PL.Controls.Add(MyTxt1);<br />
PL.Controls.Add(MyTxt2);<br />
PL.Controls.Add(MyDDL1);<br />
PL.Controls.Add(MyDDL2);<br />
<br />
}<br />
protected void MyButton_Click(object sender, EventArgs e)<br />
{<br />
string myText1 = ((TextBox)this.Page.FindControl("MyTxt1")).Text;<br />
string myText2 = ((TextBox)this.Page.FindControl("MyTxt2")).Text;<br />
string myDDL1 = ((DropDownList)this.Page.FindControl("MyDDL1")).SelectedValue;<br />
string myDDL2 = ((DropDownList)this.Page.FindControl("MyDDL2")).SelectedValue;<br />
Response.Write("Value 1 : " + myText1 + "<br />Value 2: " + myText2 + "<br />Value 3 :" + myDDL1 + "<br />Value 4: " + myDDL2);<br />
}
please don't forget to vote on the post that helped you.

Why the example in C#? The OP posted his code and he was doing it in VB. See his second post[^] in the thread...

Hi,
I have weird issue with nested data grids. I have a data grid with one template column. Inside template column I have another data grid. I am finding second datagrid control on first datagrids item_databound event and binding it. Everything works fine. But I have 3 hyperlink buttons in the child grid which I am not able to find out.
These are the things what I did
1 - Main grids item_databound event finding child grid and casting.
2 - Attaching item_databound event for child datagrid
3 - In child datagrids item_databound event, trying to find the hyper links like e.Item.FindControl() and cast to HyperLink type.
I am getting null reference exception in step 3. I tried iterating through the Controls collection for the Item. It is showing all the HyperLink's. But I am unable to find it and cast it. I have viewstate turned on in the page. Any idea's ?

Hi man,
I think you might put the event handler of child grid after binding. I have tested and it works fine..
