DetailTable with NestedView Template inside - is it possible?

Hi,

I want a RadGrid with expand/collapse functionallity.
When expanding a selected row, I want to display another RadGrid with the same functionallity, but I want to display image or some data (not a table or grid).

I read about hirarchical grids, and I need something like a grid with detailtable that has nestedview template.
Is it possible to do something like this?
Is there an implementation for expand/collapse in DetailTable?
How can I call itemcreated function for the DetailTable?

Is there any example for something like this?

Thanks!

I've added the spell checker to the tool bar and can see the function working normally except for when adding a word to the dictionary, I get the following error :-

I've seen the same error responded to in the full version, and have set the network service with the relevant write permissions, but I'm still seeing a problem with this. Can you advise?

Thanks,

"No records to display. " is not shown after rebinding empty data source to grid from client side

Team,

I am removing all data rows of grid from client side.
I wanted to show

"No records to display."

in grid.
But it does not shows empty row which contains "No records to display".
Please let me know from where I can set this empty row message from clientside?
Following is my code.
This code works if grid doesn't contain any data but if grid contains the data then it removes the row from the grid but doesn't show
"No records to display".

var mastertableview = objgrid.get_masterTableView();

mastertableview.set_dataSource({});

mastertableview.set_virtualItemCount(1);

mastertableview.dataBind();

Regards,
Sampada

<EditFormSettings UserControlName="Controles/ManteminientoGridFacturasGastos.ascx" EditFormType="WebUserControl">

<EditColumn UniqueName="EditCommandColumn1">

</EditFormSettings>

When i invoke the click event from the button insert on ManteminientoGridFacturasGastos.ascx i'm not able to capture this event on the RadGrid.

<td>

<telerik:RadButton ID="cBtnInsertar" runat="server" Text="Insertar" CommandName="Insert" Visible='<%# (DataItem is Telerik.Web.UI.GridInsertionObject) %>' />

<telerik:RadButton ID="cBtnModificar" runat="server" Text="Modificar" CommandName="Update" Visible='<%# !(DataItem is Telerik.Web.UI.GridInsertionObject) %>' />

</td>

<td>

<telerik:RadButton ID="cBtnCancelar" runat="server" Text="Cancelar"

CausesValidation="false" CommandName="Cancel" onclick="cBtnCancelar_Click" />

</td>

For example, when i push the button cBtnInsertar i want to activate the event RadGrid1_InsertCommand on RadGrid but it not invoked.

I need help.

Best regards,

Issue with hiding grid

I have a scenario as below.
There are 3 check boxes.3 textbox associated with each.Grid gets populated on entering a search value in the textbox.On selecting a row on this grid,I need to hide the grid and selected value(one column) is populated into another textbox.I am getting "Object reference not set to an instance of an object.",when I implementing the logic for hiding the grid.Checkbox checked,value entered in search textbox,grid is populated ,a row selected,second textbox populated with grid value,grid gets hidden--> after this process repeated for 2-3 times,again checking on a check box gives the error.
Please find the markup with above controls.

<table width="500px">

<tr>

<td>

<fieldset id="fssearch" runat="server">

<legend>Search </legend>

<table>

<tr>

<td>

<asp:CheckBox ID="CBFile" runat="server" Text="File No" OnCheckedChanged="CBFile_CheckedChanged"

AutoPostBack="true" />

</td>

<td>

<asp:CheckBox ID="CBname" runat="server" Text="Patient Name" OnCheckedChanged="CBname_CheckedChanged"

AutoPostBack="true" />

</td>

<td>

<asp:CheckBox ID="CBMobile" runat="server" Text="Mobile No" OnCheckedChanged="CBMobile_CheckedChanged"

AutoPostBack="true" />

</td>

</tr>

<tr>

<td>

<asp:TextBox ID="RTFileS" onkeyup="KeyUp();" runat="server" OnTextChanged="RTFileS_TextChanged" Visible="false"></asp:TextBox>

</td>

<td colspan="2">

<asp:TextBox ID="RTNameS" onkeyup="KeyUp();" runat="server" OnTextChanged="RTNameS_TextChanged" Visible="false"></asp:TextBox>

</td>

<td>

<asp:TextBox ID="RTMobileS" onkeyup="KeyUp();" runat="server" OnTextChanged="RTMobileS_TextChanged" Visible="false"></asp:TextBox>

</td>

</tr>

<tr>

<td colspan="4">

<telerik:RadGrid ID="gvPatientList" runat="server" AllowFilteringByColumn="True"

AllowPaging="True" GridLines="None" OnSelectedIndexChanged="gvPatientList_SelectedIndexChanged" >

<PagerStyle Mode="NextPrevAndNumeric" AlwaysVisible="true" />

<GroupingSettings CaseSensitive="false" />

<ItemStyle HorizontalAlign="Left" />

<HeaderStyle HorizontalAlign="Left" />

<AlternatingItemStyle HorizontalAlign="Left" />

<ClientSettings EnablePostBackOnRowClick="true">

<Selecting AllowRowSelect="true" />

</ClientSettings>

<MasterTableView AutoGenerateColumns="False" DataKeyNames="pt_regid">

<CommandItemTemplate>

<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>

</CommandItemTemplate>

<Columns>

<telerik:GridBoundColumn HeaderText="Patient Name" UniqueName="pt_name" DataField="pt_name"

AllowFiltering="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="File No" UniqueName="pt_fileno" DataField="pt_fileno"

AllowFiltering="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Mobile" UniqueName="pt_pmobileno" DataField="pt_pmobileno"

AllowFiltering="false">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<HeaderContextMenu EnableImageSprites="True" CssClass="GridContextMenu GridContextMenu_Default">

</HeaderContextMenu>

</telerik:RadGrid>

</td>

</tr>

</table>

</fieldset>

</td>

</tr>

</table>

On selecting a row on the grid,I am populating name column value to a textbox and hiding the grid as below.

protected void gvPatientList_SelectedIndexChanged(object sender, EventArgs e)

{

GridDataItem RegId = gvPatientList.SelectedItems[0] as GridDataItem;

string regid = RegId.GetDataKeyValue("pt_regid").ToString();

foreach (GridDataItem dataItem in gvPatientList.Items)

{

if (dataItem.Selected)

{

RCFName.Text = dataItem["pt_name"].Text;

}

gvPatientList.Visible = false;

}

Above mentioned checkboxes act like radio buttons and javascript for the same is as below

<script language="CS" runat="server">

private void makeRadioGroupFromCheckBoxes(IEnumerable<CheckBox> checkBoxes)

{

StringBuilder sb = new StringBuilder();

foreach (CheckBox cb in checkBoxes)

{

foreach (CheckBox innercb in checkBoxes)

{

if (innercb != cb)

{

sb.Append("document.getElementById('");

sb.Append(innercb.ClientID);

sb.Append("').checked = false;");

}

cb.Attributes["onclick"] = "if(this.checked){" + sb.ToString() + "}else{this.checked = true;}";

sb = new StringBuilder();

}

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

this.makeRadioGroupFromCheckBoxes(new CheckBox[] { CBFile, CBname, CBMobile });

}

Grid gets populated on textchanged event and 'onkeyup="KeyUp();' function of the textbox,associated with it as below.
aspx:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

var timer = null;

function KeyUp() {

if (timer != null) {

clearTimeout(timer);

}

timer = setTimeout(LoadTable, 500);

}

function LoadTable() {

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("FilterGrid");

}

</script>

</telerik:RadCodeBlock>

code behind:

protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)

{

if (e.Argument.IndexOf("FilterGrid") != -1)

{

gvPatientList.Rebind();

}

protected void RTFileS_TextChanged(object sender, EventArgs e)

{

if (!string.IsNullOrEmpty(RTFileS.Text))

{

_scheduleService = new ScheduleService();

clsSchedule clsschedule = new clsSchedule();

string search = " where OldRegnNo like '" + RTFileS.Text + "%" + "'";

gvPatientList.DataSource = _scheduleService.GetAllPatients(search);

//gvPatientList.MasterTableView.Rebind();

gvPatientList.Rebind();

}

On checkedchanged eveent of check boxes,I am making the grid visible.

protected void CBFile_CheckedChanged(object sender, EventArgs e)

{

if (CBFile.Checked)

{

RTFileS.Visible = true;

gvPatientList.Visible = true;

gvPatientList.MasterTableView.Visible = true;

gvPatientList.Rebind();

}

else

{

RTFileS.Visible = false;

}

Ajaxmanager is as below:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="gvPatientList">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="gvPatientList" LoadingPanelID="RadAjaxLoadingPanel1" />

<telerik:AjaxUpdatedControl ControlID="RCFName" />

<%--<telerik:AjaxUpdatedControl ControlID="CBFile" />

<telerik:AjaxUpdatedControl ControlID="CBname" />

<telerik:AjaxUpdatedControl ControlID="CBMobile" />--%>

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="gvPatientList" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

I hope hiding/unhiding the grid gives me the error.Please suggest your ideas on this.
Thanks,
Soumya

Strange Ajax Behavior with Radbutton RadAjaxPanel RadAjaxManagerProxy RadAjaxManager RadScriptManager

I am having the hardest time getting a RadButton to invoke a function in the code-behind file, which updates the text of the RadButton. So far I can get the button to fire with Ajax, but even though the function changes the text it is not reflected back onscreen. Furthermore, the 2nd time I click the button the page conducts a postback resulting in a view that only shows the contents of the master page. The content of the web form is blank.

Am I missing or have incorrect parameters?

Web Form RadAjaxPanel + RadButton

<telerik:RadAjaxPanel ID="Panel_MyList" RestoreOriginalRenderDelegate="true" LoadingPanelID="RadAjaxLoadingPanel_MyList" runat="server">

<telerik:RadButton UseSubmitBehavior="true" AutoPostBack="true" EnableAjaxSkinRendering="false" EnableEmbeddedSkins="false" EnableTheming="false" EnableBrowserButtonStyle="false" EnableEmbeddedBaseStylesheet="false" ButtonType="LinkButton" ID="Button_MyList" OnClick="Button_MyList_OnClick" runat="server" Text="Add to Favorites" CssClass="btn btn-view" style="font-size:18px;"></telerik:RadButton>

</telerik:RadAjaxPanel>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel_MyList" runat="server" />

Web Form RadAjaxManagerProxy

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy_Tour" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Button_MyList" EventName="Click">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="Button_MyList" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

Master Page RadScriptManager + RadAjaxManager

<telerik:radscriptmanager ID="Radscriptmanager1" EnablePartialRendering="true" EnablePageMethods="true" ScriptMode="Debug" runat="server"></telerik:radscriptmanager>
<telerik:RadAjaxManager ID="RadAjaxManager1" EnableAJAX="true" runat="server" />

Save File to Folder, File Name to Database

First of all I am very new to ASP.NET. Been writing classic ASP for 10 years.
I have a very basic insert form that is submitting to a sql database named "Users", table named "tblUsers".. I have a field named "ImageName" that I am trying to get the file name to post to when the form is submited. The image uploads but I cannot figure out how to make the file name post to the database. I am using RadUpload and I figured you could bind the field to the database column just like you do the text fields. But I don't see how. This is all very new to me. Thanks

Report or Gridview

We have purchased the Developer Tools package and I need to generate an asp.net web page that displays a report that looks similar to the attached image. I would like to use the reporting tools as we want to be able to export and print easily, but I'm having some trouble determining the best way to do this. It seems that the gridview would be a better option, but it doesn't look like there is an easy way to export and/or print the radgrid...is there?

The rows with month names are to be expanded and collapsed when the user clicks on them. What would be the best way for me to approach this using the Telerik Developer tools?

Thanks in advance.
