Forms Data Controls :: Getting Embedded Controls In Gridview To Talk To Each Other?
Jun 3, 2010
I have a grid like this. I have a checkbox in one column and a textbox in another. They are both in ItemTemplate, not in EditTemplate.
[Code]....
I am trying to get them to talk to each other in the event handler. In this scenario, when the user checks the chebox in a given row, the textbox gets filled with today's date.
How would you go about doing that? The parameters for the event handler for CheckBox are just object and EventArgs, so I have no way of passing the row id or datakey of the given row.

I had a problem with my site in the past couple days and have almost recovered, but now I'm stuck on some code that has an Auto-Complete feature, which allows a user to type a name of a pub into a TetxBox, and based on the returned names, the user can click one and see that name in the GridView (just below the TextBox). The GridView was set up so that there was an href that the user could click on and that would open a window and the user would see the pub in Google Maps. The code below works just fine for the Auto-Complete and the GridView.

Here is the end of the working code. Somehow I need to use the code below to make
the GridView have a href to allow a user to click and see the pub in Google

The code above worked fine before, but I'm not sure how it was incorporated into the GridView, and since I had a problem with my site a few days ago, I haven't been able to figure out this part.I'd sincerely appreciate any help in getting this up and running again.

I have a client who runs a music business. Part of it revolves around giving lessons. He wants me to create a site where the user can purchase a lesson or group of lessons and then schedule that lesson using an online calendar. But I've never seen anything like it. I wonder if my friends over at the ASP.NET forums have?"
So here's my question. Can I make the ecommerce portion of a site talk to a calendar? If I purchase 100 dollars worth of lessons, can I "tell" that to the calendar and then debit that account every time a user schedules a lesson?

I am a newbie at .NET technology and I would need to make exactly same thing like at this tutorial : http://msdn.microsoft.com/en-us/magazine/cc164077.aspx#S1I don't need to edit button or delete button there, just expand and collapse rows of child table. I was wondering if there is not some more simpler way how to do this because the article is from 2003 and I don't understand it so much. And when I looked around this solution I found some SilverLight solutions but I can't use them.

I was wondering if anyone has done this. I'm writing an application which parses latitude and longitude into a database. When presenting this information to users I would like them to be able to click on a button which would show them the location in google maps.
Alternatively I could just give them the link to google maps into which they can click on and open a new browser window...

I have a gridview that's inside a .ascx control that's dynamically embedded into another .ascx control, which is then called by a web form. The gridview will initially bind, but when any paging/sorting/command events are then triggered, I can't get any breakpoints inside the events to kick off. Additionally, when I look at the code-behind in the now-blank page, I see the old data sitting there.
what on earth is going on here? For edification, the .ascx page with the control is excerpted.

When I click on Add button, the controls disappear. how to recreate tables with their embedded user controls and populate the viewstate.

I have an ASP.NET page where I call this.DataBind() to bind the controls. I also have various user controls embedded. One has a drop down list, the bind statement gets called for it 2x but the sender the first time is not the drop down list.
Am I using the databind incorrectly? I use databind to get the properties of my page bound to a datasource so that I can use those properties in the declarative code.
In my DropDownList, I added if (sender == dropDownList) which solved the problem

I have created a custom required textbox control. In this control's preinit event i load a css file. Alle css and images are inside the assambly. When i use my custom control on a page the control loads fine and also the css and images are loaded. Validation of the control occures when i click the validate button. So this works perfect. But now i want to use my control in the following senario: I have a grid in an update panel. When i select a record in the datagrid i show a panel in a second updatepanel. Inside this panel i have my custom required textbox control.
The following is happening: I select a record and the panel will be made visible. The custom required textbox control is visible, but the build-in css is not loaded. As a test i have created a new testpage. On this testpage i have put my custom required textboxes in an updatepanel the css is loaded fine. So when my controls are in a panel inside a updatepanel and i set the panel to visible, the css is not loaded.

I marked it as an embedded resource, add assembly attribute to reference it and use the proper methods to include the link to that
css in html code... my page renders ok witk something like <link href='/WebResources.axd?....' />
That's when the problem appears! My control isn't using the css as it appears to not found webResources.axd
I tried directly in web browser to locate http://locahost/mysite/WebResources.axd and it came with http code 404 NOT FOUND
In my IIS i have uncheked "Verify if file exists" on my extensions mapping related to .axd I add HEAD verb in Web.Config to path WebResources.axd and the result is always the same

My Composite control implements IScriptControl interface.
ScriptReferences java script file does the client-side work, there I want to load a html file inside iFrame.
The Html file is an embedded resource:
([assembly: System.Web.UI.WebResource("Control.Resources.list.htm", "text/html")])
I pass the path of the html to the javascript file via descriptor property:
IEnumerable<ScriptDescriptor> IScriptControl.GetScriptDescriptors()
{
descriptor.AddProperty("iframe", iframe);
return new ScriptDescriptor[] { descriptor };
}
Where iframe is a string that contains the path from the webresource.
Now, in this html file I want to display few images that must be also loaded from resource.
The Question is how to access the resources from this html file?
Do I have to pass every image path as descriptor property?

I have created an asp.net usercontrol that should list users in a number of applications. For that purpose, the control renders a repeater (foreach application) which in turn renders a gridview (with users for that application).
The control renders fine, except the fact that columns in the gridview are not sortable. Nothing happens (no postback) when clicking the headers. Apparently, no JavaScript is rendered to perform the postback when clicking the header.
This is the code:

I would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.
1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.
2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.
1. Link button (on click) in the gridview footer (works fine)
protected void LinkButton1_Click1(object sender, EventArgs e)
{
string zupa1;
zupa1 = ddlSelectEmployee.SelectedValue;
try
{
DetailsView zupa = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1"); TextBox zupa2 = (TextBox) zupa.FindControl("txtInsertEmployee");
zupa2.Text = zupa1;
}
catch
{
}
DetailsView dettraining = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1");
TextBox training = (TextBox) dettraining.FindControl("txtTrainingType");
training.Text = "4";
}
2. EmptyDataTemplate.FindControl - can save record but cannot access txtInsertEmployee and txtTrainingType
DetailsView zupa = (DetailsView)gvTraining4.EmptyDataTemplate.FindControl("DetailsView1");TextBox
zupa2 = (TextBox)zupa.FindControl("txtInsertEmployee");TextBox
training = (TextBox)dettraining.FindControl("txtTrainingType");"4";

In my gridview I have a dropdown and if the user select [NO], I show a textbox under the dropdown, However, I don't like how it looks, so is there a way to open up a modal using the modalExtender or the jquery thickbox from my dropdown via the code behind?
I'm already using the thickbox on other pages via a button, but can it be done via a dropdown that is embedded within a gridview?

Im having trouble accessing controls inside the gridview. I have a formview control on a aspx page and inside this formview i have controls that are bound to a datasource. Which works hundred percent. Also inside this formview i have a gridview which i have created my own template. Gridview1 has 3 columns with textboxes in each column.
Column 1 - LogDate
Column 2 - LogBy
Column 3 - Number dialed
Now this is what im trying to do. I have a dial button inside formview1 along with 4 textboxes which has telephone numbers in it. When i click on the dial button i want the time to be populated into Textbox1 which is inside gridview1 and at the same time Textbox2 to be pupulated with the Username as well as the number must be populated into Textbox3 inside gridview1.
