RussianQuestion
I'm gonna create an Ext.Net's TreeGrid with custom nodes.
e.g :
All of TreeGrid's nodes should have a textbox at the front of itself and users should write a number at it.
See the below image :
Also, I have to get each nodes' textbox values in code behind at postback.
Could you please guide me, how I can create it with Ext.net and C# ?
Thanks.
Solution 2
I could found the answer :
<ext:TreeGrid ID="KnowledgeFieldsTreeGridWithTextBox1" runat="server" Title="Fileds "
Icon="Plugin" Height="300" AutoHeight="true" AutoExpandColumn="KnowledgeFiled">
<TopBar>
<ext:Toolbar ID="KnowledgeFieldsTreeGridWithTextBoxToolbar1" runat="server">
<Items>
<ext:ToolbarFill ID="KnowledgeFieldsTreeGridWithTextBoxToolbarFill1" runat="server" />
<ext:ToolbarTextItem ID="KnowledgeFieldsTreeGridWithTextBoxTextItem1" runat="server"
Text=" Filter : " />
<ext:TriggerField ID="KnowledgeFieldsTreeGridWithTextBox_TriggerField1" runat="server" EnableKeyEvents="true">
<Triggers>
<ext:FieldTrigger Icon="Clear" />
</Triggers>
<Listeners>
<KeyUp Fn="KnowledgeFieldsTreeGridWithTextBox_KeyUp" Buffer="250" />
<TriggerClick Fn="KnowledgeFieldsTreeGridWithTextBox_ClearFilter" />
</Listeners>
</ext:TriggerField>
</Items>
</ext:Toolbar>
</TopBar>
<Columns>
<ext:TreeGridColumn Header="Filed Name" DataIndex="KnowledgeFiledName" Width="100" Align="Center" />
<ext:TreeGridColumn Header="Score" DataIndex="KnowledgeScore" Width="200" Align="Right">
<XTemplate runat="server">
<Html>
<tpl if="values.leaf">
<input type="text" style="width:30px; text-align:left;" maxlength="5" value="{KnowledgeFiledScore}"></input>
</tpl>
</Html>
</XTemplate>
</ext:TreeGridColumn>
</Columns>
<Root>
</Root>
<Listeners>
<BeforeClick Handler="return !Ext.fly(e.getTarget()).is('input[type=text]');" />
</Listeners>
</ext:TreeGrid>
OTHER TIPS
Unfortunately, implementing these features with the current release of <ext:TreeGrid> in Ext.NET (v1.x) is annoyingly difficult. The <ext:TreeGrid> is just not setup for this type of rendering.
There's help coming in the next Ext.NET release (v2), although at this point it has not been released.
Here's a basic sample to help get you started with rendering the <input> fields.

return "Number : <input class=\"x-form-text x-form-field\" type=\"text\" value=\"" + v + "\" />";
}
return "";
};
