I've been passed a task of presenting a web based image onto which a user can place markers (symbols such as triangles, squares, circles, dotted lines etc, preferrably in preset colours). The brief was to present the users with a list of these symbols that they could select then click on the image to 'place' them (basically, custom brushes or stamps - similar to the circle and rectangle already present).

I've been going through the custom tools options but can't see if this is possible nor not.

Is it possible, or is this something that hasn't been implimented (yet)?

Thanks in advance for your response.

ImageEditor - Load blob

Hi

I have a requirement of loading images in a thumbnail rotator and on click of the thumbnail, open the image in bigger size. The user then should be able to edit the image like cropping, adding text etc and should be able to save it back to the database in the blob format.

I am successful in loading the images as thumbnails in a RadRotator control, from the database using datasource.
However, could you advise if it's possible to load the clicked image in a new RadImageEditor control in Rotator.ItemClick event. And then save it back to the database when it's edited (cropped, marked, text added etc)

Thanks

AutoCompleteBox lose tokens and functionality after form postback

Hi

Im using the AutoCompleteBox control to search items via a Web Api and selected value then stored as token. When submitting the form the saving of the tokens work fine but the token no longer appear in the box - its as if its lost from the view state. The functionality to search again is also lost from the box.

Any ideas or advise, see ASPX markup below:

<telerik:RadAutoCompleteBox runat="server" ID="RadAutoCompleteCostCenter" EmptyMessage="Search" Width="100%" ViewStateMode="Enabled" EnableViewState="true"
InputType="Token" DropDownPosition="Automatic" DropDownWidth="550" DropDownHeight="200" OnClientRequesting="autoComplete.Requesting" Skin="MetroTouch" MinFilterLength="3" >
<WebServiceSettings Method="search" Path="~/api/cost/" />
</telerik:RadAutoCompleteBox>

[Solved] Accessing a TextBox control in RadGrid <DetailItemTemplate> in client side using javascript

Hi,
I can access a TextBox control in RadGrid <DetailItemTemplate> in server side using C# [the code below works fine], but how can I access the TextBox in client side using javascript?

ASPX code:

<telerik:RadGrid ID="Grd_Pad" runat="server" GridLines="None" AllowSorting="true" AllowPaging="true" PageSize="20"AllowFilteringByColumn="true" AutoGenerateColumns="false" AllowMultiRowSelection="true" AllowMultiRowEdit="true"AllowAutomaticInserts="true" AllowAutomaticUpdates="true" AllowAutomaticDeletes="true"DataSourceID="Sql_Pad" Width="100%">

<SortingSettings SortToolTip=""/>

<FilterItemStyle Width="100%"></FilterItemStyle>

<GroupingSettings CaseSensitive="false"></GroupingSettings>

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

<MasterTableView DataKeyNames="pad_id" CommandItemDisplay="Top" EditMode="InPlace"

GroupLoadMode="Client" GroupsDefaultExpanded="true" TableLayout="Fixed" Width="100%">

<telerik:GridTemplateColumn DataField="pad_name" HeaderText="Show Hide" SortExpression="pad_name"

UniqueName="pad_showhide" CurrentFilterFunction="Contains"

ShowFilterIcon="false" FilterControlToolTip="" FilterImageToolTip="" FilterControlAltText=""

FilterControlWidth="100%">

<HeaderStyle HorizontalAlign="Left" Width="5%"/>

<ItemStyle HorizontalAlign="Left" Width="5%"/>

<ItemTemplate>

<telerik:RadButton ID="Btn_Pad_Toggle" runat="server" Text="Toggle" ButtonType="StandardButton"

ToggleType="CheckBox" AutoPostBack="true" OnClick="CsPadShowHide">

<telerik:RadButtonToggleState Text="Show"/>

<telerik:RadButtonToggleState Text="Hide" Selected="true"/>

</ToggleStates>

</telerik:RadButton>

</ItemTemplate>

</telerik:GridTemplateColumn>

<DetailItemTemplate>

<telerik:RadTextBox ID="Txt_Pad_Dtl" runat="server" TextMode="MultiLine" InputType="Text" Wrap="false"

Label="" Text='<%# Eval("pad_text") %>' EmptyMessage="None..."

BorderColor="#25A0DA" BorderWidth="1px" Width="100%" Height="200px">

</telerik:RadTextBox>

</DetailItemTemplate>

</MasterTableView>

</telerik:RadGrid>

C# code:

protected void CsPadShowHide(object s, EventArgs e)

{

RadButton btn = (RadButton)s;

GridDataItem di = (GridDataItem)btn.NamingContainer;

RadTextBox pad = di.DetailTemplateItemDataCell.FindControl("Txt_Pad_Dtl") as RadTextBox;

//pad.Display = true; // Ali - works

pad.Display = btn.SelectedToggleState.Selected;

}

Batch Editing DataFormatString Problem

Hi All,

A seemingly novice issue but I fail to figure out the solution. In my radgrid, I have cells with dataformatstring = "{0:p}", which give for example a value of 0.01 a value of 1% on the grid when batch editing. Problem occurs when I try to update the cells.

While the value includes a "%" sign, the update value then becomes string rather than decimal that is required by my data entry and returning error. I'm quite sure there should be a official work around, any advice will be much appreciated!

Best Regards.
