I'm creating a custom gridview control. so far I've been able to add custom sort arrows and an export to excel feature.
Now I want to have a textbox and a button in the header row to filter each row.
I want to extend either the boundfield or boundcolumn class to add a property that will allow me to distinguish wheter the column should have a filter textbox in the header.
I have a Gridview Custom Control (class library project). What I want to do is, add a button to the page. Once the button is clicked, I need a ModalPopupEctender to come up with a checkboxlist of all the Columns in the SQLDataSource that populates the Gridview.
Now since this is a class library project that inherits from the Gridview, I'm not sure how I can add a div at the very top of the page, with the "Choose Columns" button.
Should I create a user control that contains my Custom Gridview? Reason I want to do what I ask is because I want to reuse this in as many projects as I can, I wan this functionality built in to my dll.
I want to created a Custom Server Control (Inherited from GridView).
On the page, the GridView is DataBound to a DataSet, so I do not know at design time what columns will be present in my GridView.
Now, what I want to do is, to add a textbox in every Cell for the GridView Header row, and those textboxes will control column filtering.
i would like to create custom columns in the GridView Control.For example:After performing SQL query, there are 4 columns bound to the control:
1. ID
2. Name
3. LA
4. LE
Now, for each row, I would like to add column5. Custom - which would read LA and LE values from each row, assign them to variables vLA and vLE respectfuly, and then, I'd take vLA and vLE to perform custom calculations every time the page is displayed.I know how to make a custom colum to display calculated result, butCan someone please help me how to read LA and LE values for each row?
I want to create a custom control where I define several specifically named DIV sections. The code-behind logic of the custom control will perform operations on these named DIV sections. The page where the custom control is hosted needs to be able to add named controls to the DIV sections and perform operations on these named controls added to the DIV sections.
Let me explain a little further. In the custom control, I want to have code behind logic that fires the following Page Event and uses a condition to make one or another specifically named DIV section visible or not:
< _
ToolboxData("<{0}:BaseDetails runat=""server""></{0}:BaseDetails>") _
> _
Public Class BaseDetails
[code]...
how can I create a custom control which is able to generate the named DIV sections "DetailsNameDiv1" and "DetailsNameDiv2" where my custom control can check a condition and make one or the other visible. Also, I need to be able to add controls to these named DIV sections when I host the custom control and the control that I add to the named DIV section needs to let me set values of these controls from the code behind logic of the page (or usercontrol) where the custom control is being hosted (in my example, I am adding TextBox controls that I want to set the Text property from a SQL Data Reader).
I have currently on multiple pages a modal popup that displays the information below, we are getting to the point where we need to call this popup from multiple locations, currently i have duplicate setups on each page that i want to use it on, but its becoming a mess to manage when a change is needed.. so im looking to see if what i have within the modal popup can be turned into a control that i can call anywhere thru out the site and have just 1 setup to maintain going forward..If its possible to create a control that can then be placed within the modal popup and server the same purpose that would be great any links here is what i have within the modal popup that i have on atleast 3 pages currently..

I am trying to create a web custom control but I am unable to find the templete that should be in my projects window. I am using Visual Studio Pro and it should be there. Doc's say standard version doesn't have it but thats all I can find.
View 4 Replieshere's a situation and I would appreciate your response.
I have programmatically created the Wizard control:
Page_Load(obj s, evargs e)
{
Wizard ClaimDetailWizard = new Wizard();
foreach(int item in selectedItems)
{
//create new step
//added custom control to new step
//add step to wizard
}
//added wizard to a placeholder on a page
}
Based on List I get from Session i added new steps to my wizard To each step I had added a custom control
Each custom control in tern contains another custom Gridview Control in it.
So here's the problem when the page loads for example for two steps. All is good Wizard does what it's supposed to do.
But when I try to use sorting or paging in that custom Gridview. Somehow it displays the gridview I should see in the next step of the wizard.
Also what I'm noticing through debugging. Is that when I press next in the wizard I go back to the original page where I do all of the code specified above, and it recreates the wizzard. But it goes to the next step. Is this the way wizard supposed to work? Just doesn't seem very efficient.
I haven't worked on web applications in eight months or so (last contract work was WinForms), and I am trying to remember what I knew about custom controls. My issue is that I am replacing a developer who is gone and there isn't much doc or knowledge on-site anymore regarding at what point his code was left off. So I am figuring it out. We work with 3rd-party software API's. In an extension (a DLL), I am able to test what 3rd-party page is being navigated to and navigate to my own page instead. Let's call this page UserApproval.aspx when its the 3rd-party page, and UserApproval_mmock.aspx when it's mine (really his - the former developer's). The former developer has a line of code in the _mmock page, like so:<%@ Register TagPrefix="mockCustomCtl" TagName="TestControl" Src="~/Folder-1/Controls/MyCustomControl.ascx" %>Nowhere else in the code do I see a reference to mockCustomCtl. Shouldn't I, if the page is indeed rendering this control? Could that be where he left off - he created his own replacement page, created the custom control (I do have the source to MyCustomControl.ascx), but didn't actually put the custom control *on* the page?
View 11 RepliesI've created a custom gridview control with a custom datacontrolfield as well, which enabled me to have textboxes in the headercells of the gridview so I can filter each column value.
Now I've added textboxes to the footer row as well so I can allow users to insert data directly from the grid.
this is a portion of my gridview aspx code:
Code:
<FooterTemplate>
<asp:LinkButton ID="lbInsertCN" runat="server" CommandName="Insert" ValidationGroup="addCN" >Insert</asp:LinkButton>
<asp:LinkButton ID="lbCancelInsertCN" runat="server" CausesValidation="False" CommandName="Cancel" Text="Cancel" ></asp:LinkButton>
[Code] ....
As you can see, I added an Insert and Cancel button in the footer row. Then I have my custom column. Now in the rowdatabound event of the grid, i'm trying to hook up the linkbutton click event to a handler:
Code:
Protected Sub nsGrvContainer_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles nsGrvContainer.RowDataBound
Select Case e.Row.RowType
Case DataControlRowType.Footer
Dim lbInsert As LinkButton = CType(e.Row.FindControl("lbInsertCN"), LinkButton)
AddHandler lbInsert.Click, AddressOf odsContainerNumber_Inserting
End Select
I find the control fine, but the click event never fires.
i've created a webform with one gridview having connected with the database using datasource. i.e password database with three colomn .
now want to insert the custom dropdown button using server control for each column.
when i select the dropdown list the list should display the value as required.
e.g if i click the uname dropdownlist then it should show the list of names.
if i click on pwd dropdownlist then it should show the list of numbers.
if i select any one of the value in the dropdown list then it should insert into the
database.
can i get code on this type of question...?

I want a create a custom/user control that has children.
For Example, I want my control to have the following markup:
<div runat="server" id="div">
<label runat="server" id="label"></label>
<div class="field">
<!-- INSERT CHILDREN HERE -->
</div>
</div>
and when I want to use it on a page I simply:
<ctr:MyUserControl runat="server" ID="myControl">
<span>This is a child</span>
<div runat="server" id="myChild">And another <b>child</b>
</ctr:MyUserControl>
The child controls inside my user control will be inserted into my user control somewhere. What is the best way to accomplish this?
The functionality is similar to a asp:PlaceHolder but I want to add a couple more options as well as additional markup and the such. Also the child controls still need to be able to be accessed by the page. (in the example above the page should have the myChild Control on it)
EDIT ------
It can be a template control as long as it allows me to reference the children on the page.

I am trying to figure out how to use/create a custom control in ASP.NET MVC 2.
I created a custom control earlier and compiled it (ccontrol.dll), the control renders a div, textbox and a button + some javascript in order to post a comment on the website. It could be a static aspx page that i wanted to allow my visitors to add a comment to. I would then drag my control from the toolbar to the aspx page and run it, it would then render all the code needed on the webpage including fetching the data from a datasource and displaying that inside the div. The user could also just type in a comment and press the button to save it to the datasource.
Is this possible to convert to MVC 2? Any good tutorial that covers custom controls and MVC 2? (Ideally would be if the control could be made into a .dll file that i then could reuse on future webpages)
How do i write a custom control the mvc way? Any good tutorials on the topic?
