Hi,
I'm searching for a solution to limit the editor input to 2000 words, instead of blocking of the input, add a red line after 2000 words and the input can be continued. Same when pasting a large text, after pasting a large text, a red line have to be added after 2000 words.

Can you please help me out with this?

Kind regards,
Jelle

Selection not persisting

I have a RadComboBox that gets its data set in the FrameWorkInitialize method like this:

if (!IsPostBack)
{
string firstFilterName = adaptationFilters[0].FilterCategoryName;
var firstFilterGroup = adaptationFilters[0].FilterCategoryChoices.Select(afc => new ComboBoxItem(firstFilterName, afc)).ToList();
firstFilterGroup.Insert(0, new ComboBoxItem(firstFilterName, firstFilterName));
_filterDropDown1.DataSource = firstFilterGroup;
_filterDropDown1.DataBind();
_filterDropDown1.SelectedIndex = 0;
}

(where ComboBoxItem is an internal class that has an object, value and a string, text)

Everything looks good until I pick a value. Well, the SelectedIndexChanged event also fires like it should, but after the postback, item 0 is selected again. This happen both with ViewStateMode enabled and without.

What am I doing wrong?

[Solved] Radgrid Align columns seperately on pdf export

Hi.

I would like to align my pdf when exported in such a manner that all string columns are aligned left and numeric columns aligned right. I have tried many different ways with no such result. Below is a code snippet of what I am currently using.

private void ApplyStylesToPDFExport(GridItem item)

{

if (item is GridHeaderItem)

foreach (TableCell cell in item.Cells)

{

cell.Style["font-family"] = "Verdana";

cell.Style["text-align"] = "Left";

cell.Style["font-size"] = "12pt";

}

if (item is GridDataItem)

{

item.Style["font-size"] = "12px";

item.Style["background-color"] = item.ItemType == GridItemType.AlternatingItem ? "#DDDDDD" : "#AAAAAA";

item.Style["horizontal-align"] = "Right";

}

The method is then called in the item_created event. This code is being used to try align headings to left and data to right with not much success.

Any help would be greatly appreciated.

Kind regards.

Hide/display RadGrid columns on pre-render

I'm trying to hide/show different columns on a nested rad grid based on a flag in the pre-render event but they are all displaying

These are my grid columns:

<telerik:GridBoundColumn UniqueName="LocalDeanery" ReadOnly="true" DataField="localdeanery" HeaderText="Local Deanery" SortExpression="localdeanery"

HtmlEncode="false" >

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn UniqueName="Sector2013" HeaderText="Sector" SortExpression="hasBeenHeld desc,Sector" AllowFiltering="false" >

<ItemTemplate>

<asp:Label ID="Label2" runat="server"

Text='<%# Eval("Sector").ToString() + " (" + Eval("PrefRank").ToString() + ") " + (Eval("conditional").ToString()==""?"":"Conditional")%>'

Visible='<%# Eval("OfferId").ToString()!="" %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn UniqueName="Region" ReadOnly="true" DataField="tRegion" HeaderText="Region" SortExpression="tRegion"

HtmlEncode="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="Subregion" ReadOnly="true" DataField="tSubRegion" HeaderText="Sub-Region" SortExpression="tSubRegion"

HtmlEncode="false" >

</telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="Sector2014" ReadOnly="true" DataField="tSector" HeaderText="Sector" SortExpression="tSector"

HtmlEncode="false" >

</telerik:GridBoundColumn>

and my code in the pre-render

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

RadGrid od = (RadGrid)RadGrid1.MasterTableView.Items[0].ChildItem.FindControl("OfferDataDetail");

Label ry = (Label)RadGrid1.MasterTableView.Items[0].ChildItem.FindControl("LblRoundYear");

int RoundYear = 2014;

if (ry != null) RoundYear = int.Parse(ry.Text);

//display for 2013

od.Columns.FindByUniqueName("LocalDeanery").Visible = (RoundYear == 2013);

od.Columns.FindByUniqueName("Sector2013").Visible = (RoundYear == 2013);

//display for 2014

od.Columns.FindByUniqueName("Region").Visible = (RoundYear == 2014);

od.Columns.FindByUniqueName("Subregion").Visible = (RoundYear == 2014);

od.Columns.FindByUniqueName("Sector2014").Visible = (RoundYear == 2014);

od.Rebind();

}

The lines to hide/show the columns is being hit but they are still displaying, is there something else I should be doing?
thanks

RadAjaxManager and, UpdatePanels problem

I have a fairly complex page I have been working on but have been having some trouble of late adding some ajax to some of the page items.

The problem seems to be one of compatibility between the RadAjaxManager and the regular ASP.NET AJAX UpdatePanels.

Below I have put together a skeleton of how my page is constructed. I have stripped out all the guts of the various controls for the sake of brevity (and relevance).

In this format the page does not work. For one, clicking a row on the parent grid should make the child grids update. That does not happen. I have been on this page all day and just can't seem to get all the bits working together.

Yesterday I had an UpdatePanel around pretty much the whole page. The child grids updates but other bits started to break.

Here it is

<masterpage> << Contains the ScriptManager

<script>

// Javascript in here

</script>

<asp:UpdatePanel>

<telerik:RadWindowManager>

<telerik:RadWindow>

<asp:TabContainer>

<asp:TabPanel />

</asp:TabContainer>

</telerik:RadWindowManager>

</asp:UpdatePanel>

<asp:UpdatePanel>

<table>

[various standard form elements]

<telerik:RadComboBox />

<input type="Button"/>

</table>

</asp:UpdatePanel>

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

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="ParentGrid" />

<telerik:AjaxUpdatedControl ControlID="ChildGrid1" />

<telerik:AjaxUpdatedControl ControlID="ChildGrid2" />

<telerik:AjaxUpdatedControl ControlID="ChildGrid3" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadGrid ID="ParentGrid">

</telerik:RadGrid>

<asp:TabContainer ID="tc1" runat="server">

<asp:TabPanel ID="tp1" runat="server">

<telerik:RadGrid ID="ChildGrid1"/>

</asp:TabPanel>

<asp:TabPanel ID="tp2" runat="server">

<telerik:RadGrid ID="ChildGrid2"/>

</asp:TabPanel>

<asp:TabPanel ID="tp3" runat="server">

<telerik:RadGrid ID="ChildGrid3"/>

</asp:TabPanel>

</asp:TabContainer>

</masterpage>

One forum post I read somewhere suggested that I should not use the RadAjaxManager and instead just put UpdatePanels around all the things that need it. But that would not work for me as I have some popup forms that on closing call this bit of javascript to refresh the grids managed by the RadAjaxManager.

function refreshGrid(arg) {

$find("<%# RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");

}

So ditching the RadAjaxManager is not an option.

Could someone please suggest the correct way to set out a page like this with the RadAjaxManager?

Paging Load on Demand?

Hello,

I'm using OLAP connection to pivot grid, I have noticed that when i use the paging also Pivot Grid queries for the whole data set and displays the current page, on every page shift it does the same without using the initially retrieved data set or requesting for the current dataset. Its a huge performance hit in my case. is it possible to avoid this?

Regards,
Yohan
