Thread: Create control according to their data type

hey J

I m using repeater and so far i converted code here.see the bold part .i m not using list view .
this line Listview1.DataKeys(lvi.DisplayIndex).Value is for list view i want this line converted for repeater.

Code:

public void AddRowstoIDList()
    {
        // Loop through all the current items in the Listview
        foreach (RepeaterItem item in rptExtraInfo.Items) 
        {
            
            CheckBox chkbox = (CheckBox)item.FindControl("chkBox");
           
            if ((((chkbox) != null))) 
            {
                    int ID = Convert.ToInt32(rptExtraInfo.Items[item.ItemIndex].ItemIndex); 
                    if ((chkbox.Checked && !this.IDs.Contains(ID)))
                    { 
                        // Add the ID to our list 
                        this.IDs.Add(ID); 
                    } 
                    else if ((!chkbox.Checked && this.IDs.Contains(ID))) { 
                        // Not checked - remove the ID from our list 
                        this.IDs.Remove(ID); 
                    } 

                    
            }
            
        }

this line is not working.

Code:

int ID = Convert.ToInt32(rptExtraInfo.Items[item.ItemIndex].ItemIndex);

so can anyone tell me how to get id of check box in repeater.

You need to use the FindControl method. You can call this within the ItemCommand event or the ItemDataBound event, for example. It just depends on what you're trying to do.

hi
even my check box is checked but this always return false

Code:

  CheckBox chkbox = (CheckBox)item.FindControl("chkBox");
if (chkbox.Checked)

why??

False is the default value...I'm guessing that the checkbox hasn't yet been set in the repeater. What event is this code running in?

ok now check box issue is resolved.now i m able to maintain the state of check box.but how to maintain state of text box.The link u have given about check box is using list to maintain id.

but for text box i want to maintain id and corrsponding value .how to do this?

It's the same concept as the checkbox, but you need to store the additional value.

The checkbox example only stores the ID's of checkboxes that are checked. So you'll only want to store the ID's of textboxes that actually have text. You could store a DataTable in viewstate instead of a List. This would allow you to have two columns (id and value).

hi actually now i m using Hash table to store key and value.below code in repeater creates text boxes.in asp what we do give unqiue name to each text boxes when we create no of text boxes from database.so that we uniquelly identify them.but in .net how to identify the, uniquelly.

Code:

<asp:TextBox runat="server" Visible='<%#VisibleTextBoxYesNo(DataBinder.Eval(Container .DataItem,
                                    "DataTypeN0").ToString())%>' ID='txtBox'></asp:TextBox>

hope it make some sense.

The controls in the repeater are automatically assigned a unique ID.

i want to access that ids in one of my method.how can we access.these controls are in repeater.i want to access them in below method not in ItemCommand event or the ItemDataBound event.
public void AddRowstoIDList()
{
}
