After dynamically adding controls in the background, the script cannot obtain the Control ID.

 

After the control is dynamically added to the background, the script cannot obtain the ID of the control. You must obtain the ID using the above method.

BackgroundCode:

Public void bindnotmaincategory ()
{
Dataset DS = lifeexpress. components. poicategory. getchildcategorydataset (0 );
Notnotmaincategoryidlist. Text = ""; // enter a value in the input box.

For (INT I = 0; I <Ds. Tables [0]. Rows. Count; I ++)
{

Checkbox WPS = new checkbox ();
WPS. ID = "Chk" + Ds. Tables [0]. Rows [I] ["ID"]. tostring ();
WPS. tooltip = Ds. Tables [0]. Rows [I] ["ID"]. tostring ();
WPS. Text = Ds. Tables [0]. Rows [I] ["displayname"]. tostring ();
Panelnotmaincategory. Controls. Add (WPs); // panelnotmaincategory is a panel control

Checkboxlist chklist = new checkboxlist ();
Chklist. repeatdirection = repeatdirection. horizontal;
Chklist. ID = WPS. tooltip;
Chklist. repeatcolumns = 4;
Dataset ds1 = lifeexpress. components. poicategory. getchildcategorydataset (convert. toint32 (WPS. tooltip. Trim ()));
If (ds1.tables [0]. Rows. Count> 0)
{
Chklist. datasource = ds1;
Chklist. datatextfield = "displayname ";
Chklist. datavaluefield = "ID ";
Chklist. databind ();
If (! Panelnotmainchildcategory. Controls. Contains (chklist ))
{
Panelnotmainchildcategory. Controls. Add (chklist); // panelnotmainchildcategory is a panel control.

}
}

// Move the cursor over the control WPS to display the corresponding chklist control and hide other checkboxlist controls.

WPS. Attributes. Add ("onmouseover", "onmouseupnotmaincategory (" + chklist. clientid + ")");
Notnotmaincategoryidlist. Text = notnotmaincategoryidlist. Text + chklist. clientid + ",";

If (I = 0)
{
WPS. Checked = true;
// Chklist. Visible = true;
Chklist. style. Add ("display", "Block"); // whether to use the style Control for display and hide, without vislble.
}
Else
{
// Chklist. Visible = false;
Chklist. style. Add ("display", "NONE ");
}
}
If (notnotmaincategoryidlist. Text. length> 0)
{
Notnotmaincategoryidlist. Text = notnotmaincategoryidlist. Text. substring (0, notnotnotmaincategoryidlist. Text. Length-1 );
}
}
