Highlight the grid line in the update panel without sending back

Question

I have a gridview in the update panel with the following code to select a row, this, in turn, updates another update panel with data from the form record.

protected void gvMainGrid_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            //Make the entire row clickable to select this record
            //Uses javascript to post page back
            e.Row.Attributes["onmouseover"] = "this.style.cursor='hand';this.style.textDecoration='underline';";
            e.Row.Attributes["onmouseout"] = "this.style.textDecoration='none';";
            e.Row.Attributes.Add("onclick", ClientScript.GetPostBackClientHyperlink(this.gvMainGrid, "Select$" + e.Row.RowIndex));   

        }
    }

I manually bind gridview to the database and don’t want to rebuild the grid just to highlight the row, but I can’t add javascript to the onclick event, it seems either shows GetPostBackClientHyperlink or the string underlines javascript.

Answer 1

I struggled to add both click events to the string binding string:

e.Row.Attributes.Add("onclick", ClientScript.GetPostBackClientHyperlink(this.gvMainGrid, "Select$" + e.Row.RowIndex));   

e.Row.Attributes.Add("onclick", "onGridViewRowSelected('" + e.Row.RowIndex.ToString() + "')");

Adding the PostBack method after selecting the line selection method with ;; seems to have worked.

e.Row.Attributes.Add("onclick", "onGridViewRowSelected('" + e.Row.RowIndex.ToString() + "');" + ClientScript.GetPostBackClientHyperlink(this.gvMainGrid, "Select$" + e.Row.RowIndex));

gridview

OnRowCreated, OnRowDataBound ...

    protected void ctlGridView_OnRowCreated(object sender, GridViewRowEventArgs e)
    {    
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onclick", "onGridViewRowSelected('" + e.Row.RowIndex.ToString() + "')");
        }            
    }

script

<script language="javascript" type="text/javascript">
    var gridViewCtlId = '<%=ctlGridView.ClientID%>';
    var gridViewCtl = null;
    var curSelRow = null;
    function getGridViewControl()
    {
        if (null == gridViewCtl)
        {
            gridViewCtl = document.getElementById(gridViewCtlId);
        }
    }

    function onGridViewRowSelected(rowIdx)
    {
        var selRow = getSelectedRow(rowIdx);
        if (curSelRow != null)
        {
            curSelRow.style.backgroundColor = '#ffffff';
        }

        if (null != selRow)
        {
            curSelRow = selRow;
            curSelRow.style.backgroundColor = '#ababab';
        }
    }

    function getSelectedRow(rowIdx)
    {
        getGridViewControl();
        if (null != gridViewCtl)
        {
            return gridViewCtl.rows[rowIdx];
        }
        return null;
    }
</script>
