RadGrid NeedDataSource firing before rebind()

Hi,

I have a radgrid with a lazy load method to handle the binding. The binding is done via a button's CustomParameter that, when it's clicked, provides the parameters for the query that populates the grid. Problem is: the Grid's NeedDataSource is triggered before the rebind call on the button's click event and messes up the whole thing.

Here is the grid NeedDataSource, where the 'bind' variable is to prevent the call when first accessing the page

protected void Quotas_Table_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

if (bind && Session["SessionId"] != null)

{

Quotas_Table.DataSource = Empresas_DAL.GetQuotasList((string)Session["TP_QT_" + (string)Session["SessionId"]], int.Parse((string)Session["PRD_QT_" + (string)Session["SessionId"]]), DateTime.Now.Year);

}

and here is the button's event, where all variables here are strings:

protected void Compilar_Click(object sender, EventArgs e)

{

LinkButton lnk = sender as LinkButton;

string param = lnk.Attributes["CustomParameter"];

tipo = param.Substring(0, 1);

periodo = param.Substring(1);

Session["TP_QT_" + (string)Session["SessionId"]] = tipo;

Session["PRD_QT_" + (string)Session["SessionId"]] = periodo;

bind = true;

Quotas_Table.Rebind();

}

Change display order for statically created panels

Hi

Is it possible to change in the code behind the order for statically created panels?

The only way I can think of doing it is to create each panel as a user control, and dynamically add them.

RadWindow OnClientClose is undefined

Hello Telerik Team,

I am getting one error in javascript displaying as "OnClientClose " is undefined.

Below are the steps.
1) I am opening a popup through the below code:

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" VisibleStatusbar="false" >

<Windows >

<telerik:RadWindow ID="TaskList" runat="server" Title="TaskList" modal="true"

OnClientClose="OnClientClose"></telerik:RadWindow>

</Windows>

</telerik:RadWindowManager

//Call a javacript code

<script type="text/javascript">

function OnClientClose(oWnd, args)

{

oWnd.setUrl("XYZ.aspx");

}

</script>

Till here its no problem it works perfectly, but as soon as I put this line of of code in javascript shown below
< src="../../includes/validate.js">

It fires the above message saying OnClientClose is undefined on status bar of IE.
If removed the above line again it works perfectly.

Can anyone Please suggest any solution for this.

Move Labels on Bar Chart with Negative Values

Hello,

I have a bar chart (attached) the labels need to be moved outside the chart on the left so they are not covering the bars.

I have seen this as an issue going back to 2012 in the forums.. Its 2017 so I cant imagine this is still an issue.

If it is still an issue what is the work around? Is there a hack? I looked to see if I could use CSS but it does not seem so.

I tried AxisCrossingValue... it moves the bars so they don't line up with the correct X-Axis Labels... so that does not work.

I really need this to work.

Thanks,

Charles

RadAsyncUpload call with buttons in RadGrid

I have a RadAsyncUpload somewhere on a page and a RadGrid in the same page.The RadGrid has a column for every row that is a LinkButton which executes a grid ItemCommand. The ItemCommand fetches the ID associated to the row and stores it in a session variable. I want the item command to also then bring up the RadAsyncUpload window so the user could select files.

The way I tried to achieve this so far is by calling a javascript function which finds the RadAsyncUpload control and performs a button click. This does not happen after postback, however.

It is crucial to me that each file I upload is associated with a row ID. Is there a way I can achieve this scenario or am I limited by the RadAsyncUpload controls functionality?

Change background color of each Bar

I am trying to change the background colors of individual bars to red and green

TryCast(RadHtmlChart1.PlotArea.Series(0), BarSeries).SeriesItems(0).BackgroundColor = System.Drawing.Color.Red.

Chart works great and I am binding to a datatable

RadHtmlChart1.DataSource = DifferenceDT
RadHtmlChart1.DataBind()

The error is on SeriesItems (Out of Range) and count is 0 when I inspect.

Am I doing something wrong?

Here is my .aspx code

<telerik:RadHtmlChart ID="RadHtmlChart1" runat="server" Style="width: 100%; height: 98%;">

<PlotArea>

<Series>

<telerik:BarSeries DataFieldY="Count" Name="Count" >

<LabelsAppearance>

<TextStyle Color="White" />

</LabelsAppearance>

</telerik:BarSeries>

</Series>

<XAxis DataLabelsField="Name" >

<LabelsAppearance>

<TextStyle Color="White" />

</LabelsAppearance>

<MinorGridLines Visible="false" />

</XAxis>

<YAxis AxisCrossingValue="0" Step="1" >

<MinorGridLines Visible="false" />

<LabelsAppearance>

<TextStyle Color="Blue" />

</LabelsAppearance>

</YAxis>

</PlotArea>

</telerik:RadHtmlChart>
