Disable Add New button of RadGrid when no data is selected from RadCombox (which is outside of RadGrid)

There is a RadComboBox (outside of RadGrid) and a RadGrid in my Web page.

When first time page loads, and user forgets to Select Item from RadComboBox (which is outside of RadGrid) and clicks on "Add New" button of RadGrid then this button should disable at that time and an alert should come ('Select item from RadComboBox first')

Now, when user select the item from RadComboBox, and then click on "Add New" button of RadGrid then it should perform "add" functionality //---this part is done

Below code is working fine only to disable the "Add New" button and show alert.

GridCommandItem cmditem = (GridCommandItem)RGGSTAcCode.MasterTableView.GetItems(GridItemType.CommandItem)[0];

System.Web.UI.WebControls.Button ctrl = (System.Web.UI.WebControls.Button)cmditem.FindControl("AddNewRecordButton");

ctrl.Enabled = false;

ctrl.Attributes.Add("onClick", "test()");

System.Web.UI.WebControls.LinkButton btn = (System.Web.UI.WebControls.LinkButton)cmditem.FindControl("InitInsertButton");

btn.Enabled = false;

btn.Attributes.Add("onClick", "test()");

But how to create this whole requirement using above code? Where to put this line of code, in which event, so that it should work as per need.

Below is the whole HTML code I am using currently:

<telerik:RadComboBox ID="ddlCompany" runat="server" Height="200" Width="240"

DropDownWidth="310" EmptyMessage="- Select Product -" HighlightTemplatedItems="true" CausesValidation="false"

Filter="StartsWith" AppendDataBoundItems="true" AllowCustomText="true" AutoPostBack="true"

DataTextField="Title" DataValueField="Code" OnSelectedIndexChanged="ddlCompany_SelectedIndexChanged">

</telerik:RadComboBox>

<br />

<telerik:RadGrid ID="RGGSTAcCode" runat="server"

ShowFooter="True" GroupingEnabled="False" ShowStatusBar="true" EmptyDataText="No record available."

AllowAutomaticInserts="False" AllowAutomaticUpdates="False" AllowAutomaticDeletes="true"

OnNeedDataSource="RGGSTAcCode_NeedDataSource" OnItemDataBound="RGGSTAcCode_ItemDataBound"

OnInsertCommand="RGGSTAcCode_InsertCommand" OnDeleteCommand="RGGSTAcCode_DeleteCommand"

OnUpdateCommand="RGGSTAcCode_UpdateCommand">

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

<mastertableview ShowHeadersWhenNoRecords="true" autogeneratecolumns="false" datakeynames="AccountCodeID" InsertItemDisplay="Top"

insertitempageindexaction="ShowItemOnCurrentPage" ShowFooter="True" CommandItemDisplay="Top">

<Columns>

<telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn"></telerik:GridEditCommandColumn>

<telerik:GridTemplateColumn UniqueName="AccountCode" HeaderText="Account Code">

<ItemTemplate>

<asp:Label ID="lblAcCode" Text='<%# Eval("AccountCode") %>' runat="server"></asp:Label>

</ItemTemplate>

<EditItemTemplate>

<asp:DropDownList ID="ddlAcCode" DataTextField="AccountDescription" DataValueField="AccountCodeID" runat="server"/>

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn DataField="AccountDescription" HeaderText="Description" UniqueName="AccountDescription" SortExpression="AccountDescription" InsertVisiblityMode="AlwaysHidden" ReadOnly="true" ></telerik:GridBoundColumn>

<telerik:GridBoundColumn aggregate="SUM" DataField="Amount" HeaderText="Amount" FooterText="Total : " UniqueName="Amount" SortExpression="Amount"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Remark" HeaderText="IFCA Remark" UniqueName="Remark" SortExpression="Remark">

</telerik:GridBoundColumn>

<telerik:GridButtonColumn ConfirmTextFormatString="Are you sure you want to Delete {0} Account Code?" ConfirmTextFields="AccountCodeID"

ConfirmDialogType="RadWindow" CommandName="Delete" Text="Delete" UniqueName="DeleteColumn"></telerik:GridButtonColumn

</Columns>

<EditFormSettings>

<EditColumn ButtonType="ImageButton" />

</EditFormSettings>

<CommandItemSettings AddNewRecordText="Add new record" RefreshText="Refresh"></CommandItemSettings>

</mastertableview>

</telerik:RadGrid>

Please guide.

Please note that I am very new in Telerik controls so if I ask something very basic please forgive and try to guide me in a simple way.

RadInput - User arrow keys to navigate to next input

I have written a javascript function that allows the enter key to navigate to the next input on a large form that I have and I would like the up & down arrow keys to have the same functionality, however I believe the built in arrow key increment settings in the RadNumericTextbox are interfering with this. I have set the InterceptArrowKeys setting to False and am trying to capture the entered key with the ClientEvents.OnKeyPress event but it is not firing. Any ideas on how to accomplish this?

Populate HTMLChart from RadGrid Row

How would I go about populating an HTMLChart with the selected row within my RadGrid? Upon a user selecting a row, I need the points on the graph mapped accordingly. Need the dates across the X axis and amounts going up the Y axis.

This example is what I want but not looking to query the database just use the records already returned.

Appreciate your help.

Telerik grid Calculated column

I've got a radGrid that allows paging. I have a grid calculated column in the grid. If user clicks on the next page or user changes the page size , the following error message displays:

Sys.WebForms.PageRequestManagerServerErrorException: An item with the same key has already been added.

If we are commenting the grid calculated columns paging is working fine.

Thanks

Treeview empty after repeated web service calls

Hi,

Let me describe the scenario.

I have a page with a treeview on the left side and a diagram (using a 3rd party tool) on the right.

The treeview is built in code behind and is not modified on the client.

The user right-clicks on a shape on the diagram and selects an item from a context menu.

This causes a radWindow to open. When the user clicks on Save, a web service is called to update the database.

The window is closed and everything is fine.

However, if the user opens the radWindow and clicks Save four times (or more) and then clicks on a button to navigate to the next diagram, an error occurs:

System.ArgumentOutOfRangeException: Index was out of range

I have put a break in my code behind where the error is occurring and it appears that the treeview is suddenly empty - no nodes!!

There is nowhere in the scenario I presented above where the treeview is touched in any way, so I'm at a loss as to how it became empty.

Could this possibly be session related? I'm not familiar enough with web services (using an asmx file) to know whether the web service could be affecting the same session storage that is used by the trreeview.

Is there any other reason that the treeview would suddenly be empty?

I can post code snippets, but I'm afraid that might be overwhelming for this forum.

Any ideas? Suggestions for debugging?

Thanks in advance.

Jim

Batch edit: Javacript error with values containing apostrof/quote (')

Hello,

Version: 2015.0001.0401.0045

When using batch edit, and changing a cell's value to a value containing a apostrophe/quote ( ' ) or 2, and pressing "Save Changes", the __doPostback function failed with error: Uncaught Syntax Error: missing ) after argument list.

The output of the function is like this:

__doPostBack('RadGrid_TimeReg','FireCommand:RadGrid_TimeReg$ctl00;BatchEdit;u(0,.,ProjectList,.,Jasper - Werk Order #0005 'Jasper' (52),.,TimeKindInfo,.,Ontvetten,.,);.;')

As you can see, 'Jasper' breaks the code.

I consider this a bug.

Kind regards,

Erik
