[CLOSED] [1.0] Selectable Property

[vali1993]

Thank you :)

My questions are:

1. if set Selectable="false" in <default> on a formpanel with 30 textboxes,
one of those textboxes is not ready only, Do I have to set selectable property individually for all controls? (set Selectable="true" for that textbox doesn't seem to work)

2. I need to set selectable=true/false based on DB result, default state is all ready on
ly. "txt1.Selectable = true;" in page_load doesn't seem to do anything.

<ext:FormPanel runat="server" Title="Width=0.25" Html="This is some content."><Defaults>
<ext:Parameter Name="selectable" Value="false" Mode="Raw" />
<ext:Parameter Name="anchor" Value="95%" />
</Defaults>
<Items>
<ext:TextField runat="server" ID="txt1" Selectable="true"/>
<ext:TextField runat="server" ID="txt2"/>
<ext:TextField runat="server" ID="txt3"/>
</Items>
</ext:FormPanel>

Hi vali1993,

Yes, this scenario is a bit of a problem. We are discussing some options.

At the moment, the best we can recommend is using the <CustomConfig> inner property to force the "selectable" property to render.

Example

<ext:FormPanel runat="server" Title="Width=0.25" Html="This is some content.">
    <Defaults>
        <ext:Parameter Name="selectable" Value="false" Mode="Raw" />
        <ext:Parameter Name="anchor" Value="95%" />
    </Defaults>
    <Items>
        <ext:TextField runat="server" ID="txt1" Selectable="true">
            <CustomConfig>
                <ext:ConfigItem Name="selectable" Value="true" Mode="Raw" />
            </CustomConfig>
        </ext:TextField>
        <ext:TextField runat="server" ID="txt2" />
        <ext:TextField runat="server" ID="txt3" />
    </Items>
</ext:FormPanel>

I'll keep you updated with our progress.

As a bit of a side note, when configuring in markup, you can now add the "Default" keyword before any property name and it will automatically add that property to the <Defaults> when serializing to the client.

Here's the same sample as above, but without the inner <Defaults>.

Example

<ext:FormPanel 
    runat="server" 
    Title="Width=0.25" 
    Html="This is some content." 
    DefaultSelectable="false" 
    DefaultAnchor="95%">
    <Items>
        <ext:TextField runat="server" ID="txt1" Selectable="true">
            <CustomConfig>
                <ext:ConfigItem Name="selectable" Value="true" Mode="Raw" />
            </CustomConfig>
        </ext:TextField>
        <ext:TextField runat="server" ID="txt2" />
        <ext:TextField runat="server" ID="txt3" />
    </Items>
</ext:FormPanel>

The "Defaults*" properties will not show up in intellisense, but they
will render correctly. Although .DefaultAnchor is actually a property, so it will show up in intellisense.


This is more of a hidden trick for optimizing markup syntax.

Thanks Geoffrey, that is a great tip.
I tried adding this in the code behind , doesn't seem to work. do you see i am doing something wrong here. thanks again

txt1.CustomConfig.Add(new ConfigItem("Selectable","true", ParameterMode.Raw));

Hi,

Please use camel case "selectable"
We are thinking to add automatic name conversation

[vali1993]

Thanks!! it works! :)

[geoffrey.mcgill]

ok, we've added another cool hack/trick...

If you add an "X" in front of any property value, the "X" will force the property to render.

Here's your original sample now using all the markup syntax optimizations.

Example

<ext:FormPanel 
    runat="server" 
    Title="Width=0.25" 
    Html="This is some content." 
    DefaultSelectable="false" 
    DefaultAnchor="95%">
    <Items>
        <ext:TextField runat="server" ID="txt1" XSelectable="true" />
        <ext:TextField runat="server" ID="txt2" />
        <ext:TextField runat="server" ID="txt3" />
    </Items>
</ext:FormPanel>

You can still continue to use the <CustomConfig> in markup.

If you want to override the value in code-behind, you *must* use the CustomConfig collection as you demonstrated above.

This is only a markup trick.

Hope this helps.

perfect! Thanks again!

[vali1993]

Thank you for you help. one more question on this, if 'txt1' is a value from database,
is there a way i can still use this method?
txt1.CustomConfig.Add(new ConfigItem("Selectable","true", ParameterMode.Raw));
