[CLOSED] Checkbox Selected Rows in GridPanel

[speedstepmem4]

Hi,

The following process used to get selected rows [if click on Check Box] from GridPanel in Code Behind. I cant able to get selected rows using this source.

I will call confirm from code behind to check some validation.
The following source i have used in ASPX page.

function Export() {
GridData.setValue(Ext.encode(GridPanel1.getRowsValues(true, false, false, false)));
}
function Confirm() {
Export();
btn_confirm.fireEvent('click');
}
 
<ext:StoreID="St1"runat="server">
<Reader>
<ext:JsonReader>
<Fields>
<ext:RecordFieldName="NO">
</ext:RecordField>
<ext:RecordFieldName="DESC">
</ext:RecordField>
</Fields>
</ext:JsonReader>
</Reader>
</ext:Store>
 
<ext:GridPanelID="GridPanel1"runat="server"StoreID="St1"StripeRows="true"
Height="68"Header="false"Width="280"Border="true"AutoScroll="true">
<ColumnModel>
<Columns>
<ext:ColumnDataIndex="NO"Header="No"ColumnID="NO"Hidden="true">
</ext:Column>
<ext:ColumnDataIndex="DESC"Header="Kind"ColumnID="DESC"Hidden="false"
Width="230">
</ext:Column>
</Columns>
</ColumnModel>
<SelectionModel>
<ext:CheckboxSelectionModelID="CheckboxSelectionModel1"runat="server">
</ext:CheckboxSelectionModel>
</SelectionModel>
 
</ext:GridPanel>
 
<ext:ButtonID="btn_confirm"runat="server"Hidden="true">
<AjaxEvents>
<ClickOnEvent="BeforeConfirm"ShowWarningOnFailure="false"Timeout="120000">
</Click>
</AjaxEvents>
</ext:Button>
 
<ext:HiddenID="GridData"runat="server">
</ext:Hidden>

The following source i have used in code behind.

public void BeforeConfirm(object sender, AjaxEventArgs e)
    {
 
            string gridJson = GridData.Value.ToString();
            Dictionary<string, string>[] dic = JSON.Deserialize<Dictionary<string, string>[]>(gridJson);
            string strAdd = string.Empty;
            string strTempNo = string.Empty;
            string strTempDesc = string.Empty;
            foreach (Dictionary<string, string> row in dic)
            {
                row.TryGetValue("NO", out strTempNo);
                row.TryGetValue("DESC", out strTempDesc);
            }
}

When i use this source to get the value from gridpanel. But It is not working to returns the selected rows.
Please help me to fix this process
