Synchronize checkboxes in a GridVIew

Imagine this scenario, you have a GridView where it contains various columns as checkboxes and u want to impose a constraint that restrict the user from selecting a specific checkbox while the others are selected. ( by Unchecking the other checked checkboxes)

The following function takes as parameters GridView ID and CheckBox ID ( the one that when clicked uncheck the other checkboxes in a specific row in the gridview).

 

 

private void SynchCheckBoxes(string gridName, string checkboxName)     {         GridView grid = (GridView)this.Page.FindControl(gridName);         if (grid == null)         {             foreach (Control ctl in Page.Controls)             {                 if (ctl.HasControls())                 {                     grid = (GridView)ctl.FindControl(gridName);                 }             }         }         for (int y = 0; y < grid.Rows.Count; y++)         {             StringBuilder s = new StringBuilder();             CheckBox c3 = new CheckBox();             ArrayList t = new ArrayList();             int index = (int)grid.DataKeys[y].Value;             c3 = (CheckBox)grid.Rows[y].FindControl(checkboxName);             foreach (Control ctrl in grid.Rows[y].Controls)             {                 if (ctrl.HasControls())                 {                     foreach (Control ctrls in ctrl.Controls)                     {                         if (ctrls.GetType() == typeof(CheckBox) && ctrls.ID != checkboxName)                         {                             t.Add(ctrls);                         }                     }                 }             }             for (int i = 0; i < t.Count; i++)             {                 CheckBox c = (CheckBox)t[i];                 c.Attributes.Add("onclick", "document.getElementById('" + c3.ClientID + "').checked = false;");                 s.Append("document.getElementById('" + c.ClientID + "').checked = false;");             }             c3.Attributes.Add("onclick", s.ToString());         }     }

 

Have fun optimizing it!
