want to filter second grid by first grid filtering options

HI,
I want to filter second grid by first grid(rgrdcontrireport) filtering options.
I have two grids ,when i filter first grid with that filtering option i want to filter second grid also
suppose in first grid i have batchid,userid,familyid. and i filtered first grid by batchid>12,
now this filtering i want to apply to second grid(rgrdexport)
how can i do this?
i am working on this code to get value of filtering but it is not applying to second grid(rgrdexport)
first grid (rgrdcontrireport)
second grid (rgrdexport)

rgrdexport.AllowFilteringByColumn = true;
        GridColumn batchidexport = rgrdexport.MasterTableView.GetColumnSafe("BatchId");
        GridColumn batchid = rgrdcontrireport.MasterTableView.GetColumnSafe("BatchId");
        batchidexport.CurrentFilterFunction = batchid.CurrentFilterFunction;
        batchidexport.CurrentFilterValue = batchid.CurrentFilterValue;
       // rgrdexport.Rebind();
        expression = "BatchId " + batchid.CurrentFilterFunction + " " + batchid.CurrentFilterValue;
        rgrdexport.MasterTableView.FilterExpression = rgrdcontrireport.MasterTableView.GetColumnSafe("BatchId").EvaluateFilterExpression();

loop through diamically created checkbox column problem - can't find checkbox control on the page

We have a diamically created radgrid with lots checkbox column in it. They all display fine. But I have problem for looping through it and get it's value. It seems can't find the checkbox control on the page. Not sure where I missed.

foreach (Functions function in CurrentUserFunctionList)

{

// Set up the RadGrid's columns

// NOTE: We have to use a custom TemplateColumn, because each checkbox is its own unique control, with its own unique ID.

GridTemplateColumn gtcFunction = new GridTemplateColumn();

gtcFunction.HeaderText = function.Description;

gtcFunction.DataField = function.FunctionId.ToString();

gtcFunction.ReadOnly = false;

gtcFunction.AllowFiltering = false;

// NOTE: The FunctionId gets passed in because it's part of each checkbox control's ID...

gtcFunction.ItemTemplate = new RadGridCheckBoxTemplate(function.FunctionId.ToString());

rgWeb.MasterTableView.Columns.Add(gtcFunction);

// Set up the Data Table's columns

DataColumn thiscolumn = new DataColumn();

thiscolumn.Caption = function.Description;

thiscolumn.ColumnName = function.FunctionId.ToString();

thiscolumn.ReadOnly = false;

thiscolumn.DataType = System.Type.GetType("System.Boolean");

MyDataTable.Columns.Add(thiscolumn);

}

public class RadGridCheckBoxTemplate : System.Web.UI.ITemplate

{

private string colname;

/// <summary>

/// This class sets up a Template with dynamically named CheckBoxes in the RadGrid. cName is the unique identifier for th column,

/// which is added to the ID of each CheckBox control.

/// </summary>

/// <param name="type"></param>

public RadGridCheckBoxTemplate(string cName)

{

this.colname = cName;

}

/// <summary>

/// Create the template

/// </summary>

/// <param name="container"></param>

public void InstantiateIn(System.Web.UI.Control container)

{

CheckBox checkbox = new CheckBox();

//checkbox.AutoPostBack = true;

checkbox.DataBinding += new EventHandler(boolValue_DataBinding);

checkbox.ID = "cbox_" + colname;

checkbox.CheckedChanged += new EventHandler(ToggleRowSelection);

container.Controls.Add(checkbox);

}

void boolValue_DataBinding(object sender, EventArgs e)

{

CheckBox cBox = (CheckBox)sender;

GridDataItem container = (GridDataItem)cBox.NamingContainer;

cBox.Checked = (bool)((DataRowView)container.DataItem)[colname];

}

/// <summary>

/// Check and uncheck

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

void ToggleRowSelection(object sender, EventArgs e)

{

((sender as CheckBox).Parent.Parent as GridItem).Selected = (sender as CheckBox).Checked;

}

I need to loop throug the radgrid to get all the column,

use CheckBox cb = (CheckBox)gdi.FindControl(controlname);
or :

foreach (Control ctrl in Page.Controls)

{

if (ctrl is CheckBox)

{

string a = ctrl.ID;// never comes here to show the control id

}

I can't find any chekbox control on my page, not sure why?

Working with RadGrid and TemplateColumns in ItemCommand

Telerik,

Im trying to get the value of a TemplateColumn item when the ItemCommand event is raised. My TemplateColumn looks like the following:

<telerik:GridTemplateColumn HeaderText="User" UniqueName="User" Reorderable="false" Display="true" SortExpression="User">

<ItemTemplate>

<asp:LinkButton ID="btnButton1" runat="server" ToolTip="Edit this user" CommandName="EditUser" Visible="<%# Master.UserPrefs.HasEditRights %>"><%# Eval("User") %></asp:LinkButton>

<asp:Label ID="lblLabel1" runat="server" Visible="<%#!Master.UserPrefs.HasEditRights %>"><%# Eval("User") %></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

Basically, the template is built using a boolean value (determining if the current user logged in has EditRights to the record) to either display a LinkButton (to launch a custom edit screen) or to display a Label (if the current user doesn't have the appropriate permission).

In the ItemCommand, I would like to get the value of the data bound to either the Label or the LinkButton. The closest I got to getting the information is by doing something like the following:

protected void gvUsers_ItemCommand(object sender, GridCommandEventArgs e)

{

RadGrid grid = (RadGrid)sender;

switch (e.CommandName.ToUpper())

{

case "MyCommandName":

foreach (GridDataItem item in grid.MasterTableView.Items)

{

string cellContent = ((GridLinkButton)item.Cells[3].Controls[0]).Text

}

		      break;

        }

}

Is this the only way to get the Text value of the GridLinkButton? Can you please provide any other information for retrieving the values associated with a TemplateColumn using the markup in my Template?

Thanks

DatePicker Runtime Error when Date is outside of Min/Max date

I add datepicker to webform
set min date to 1/1/1900
set max date to 12/31/2099
user opens webform on existing record with date of 1/15/2300 (outside min/max date)
a runtime error occurs.

Question(s):
Why the runtime error? this is causing us grief. why doesn't validation just trigger on the datepicker control and display a validation error in the ui?
If i add the datepicker to 100s of forms, do i really have to add try/catch error handling for each when setting the date value of the control? this is a real pain.

Select multiple checkboxes in a RadGrid based on a value from a dropdownlist

Hi,

Does any one know to select multiple checkboxes in a RadGrid? I have a .net webpage, it has a dropdownlist which has values(1,2,3,4,5,6). When I select a value from the dropdownlist it should select the same number of checkboxes in the RadGrid, starting from first row. I tried to write some clientside javascript code to capture the value and then set it to the rows in RadGrid. Does anyone know how you can achive this. Help will be appreciated.

Thanks,
Raji
