Forms Data Controls :: Accessing A Child "LinkButton Inside Control's HeaderTemplate"

Nov 19, 2010

I am using an event calendar control (not a MS control) and I am trying to access a LinkButton inside this control's HeaderTemplate. Below is what I have tried so far. I get the familiar "Object reference not set to an instance of an object" error. Does anyone has an alternate way to get this control? I need to change the visibility property of it.

<ec:EventCalendar runat="server" ID="eventscalendar"...
<HeaderTemplate>
<table border="0" cellpadding="0" cellspacing="0" width="100%">
<tr>
<td style="text-align: left; width: 33%; font-weight: bold; font-size: small; color: blue">
«
<asp:LinkButton ID="PrevMonth" runat="server" Text='Previous Month' CommandName="PrevMonth" />
</td>
...
</HeaderTemplate>
LinkButton PrevMonth = (LinkButton)form1!eventscalendar.FindControl("PrevMonth") as LinkButton;
LinkButton PrevMonth = this.FindControl("form1!eventscalendar!HeaderTemplate!PrevMonth") as LinkButton;

Data Controls :: Dynamically Add LinkButton Inside Nested (Child) GridView

May 7, 2015

I am requested by my manager to develop a web page called staff deployment plan that will involve two GridViews, that is the Parent GridView and Child GridView. The Parent GridView will display two columns which are EmployeeNames and WorkingDays - the working days column is a heading of Child GridView and the child gridview displays columns as current working days for example: the month of November 2014 has 20 working days excluding weekends and public holidays in South Africa, so the columns for child gridview are like this:

3 Nov, 4 Nov, 6 Nov...etc

The problem that am experiencing now:

Is to add LinkButton for each column on the Child GridView and to create command event for each linkbutton inside a child gridview (remember this child gridview is inside a parent gridview) and the link button when is click it should display a popup window.

Accessing Tablerow Child Control By Type

Aug 11, 2010

I'm iterating through a collection of asp:tablerows to be able to get or set the text in a textbox that is nested in the third cell of the row; I'm doing this by type rather than by ID because the cell ID's in that column aren't totally consistent--thus I can't really call FindControl() to achieve this. I've resorted to casting the third control in the TableRow to a TableCell and then Casting the first control in that cell to a TextBox. Not quite correct, as I'm getting an index out of range exception thrown. The problem mainly lies in the Controls.Count() property of the third cell, which comes to zero. Not sure if there's a better way to access the textbox---should I resort to FindControl()?

foreach (TableRow row in tblProviders.Rows) {
string value = ((TextBox)((TableCell)row.Controls(2)).Controls(0)).Text;
...
}

My searches here only yielded use of FindControl(), so that may be the only way...

I have an ItemTemplate inside a listview with a linkbutton wrapped around three table rows. The linkbutton is supposed to make the whole rows clickable but this only works in IE. Does anyone have an idea about why? The link works if I move the rows out of the linkbutton and write some gibberish text instead, but that's not what I want.

Javascript - Accessing Child Control Of A Gridview From Java?

Feb 24, 2011

The below code works, I'm just curious if there is a dynamic way to pass the generated GridLeft__ctl1_GridViewLeftSearch ID into the javascript function.

<HeaderTemplate>
<asp:TextBox ID="GridViewLeftTextBox" Width="80%" runat="server"
onKeyPress="javascript:SearchLeft(event);"></asp:TextBox>
<asp:Button ID="GridViewLeftSearch" runat="server" Width="100%"
OnClick="onSearchLeftGrid" Text="Search Patients" Font-Size="Small">
</asp:Button>
</HeaderTemplate>

Is their a way to access The GridViewLeftSearch Button inside this Javascript function without hard coding it?

function SearchLeft(e) {
var t = document.getElementById("GridLeft__ctl1_GridViewLeftSearch");
if (t != null) {
t.click();
}
}

UserControl - Accessing A Child Control In The Parent Page?

Nov 3, 2010

If for example my userControl has a CheckBox called IsGreatCoder and the userControl is embedded in a main page (parent page).

I normally have gained access to the IsGreatCoder.Checked value in the main-page by exposing it through a public property that I have to manually write (say "IsAGreatCoder").

If UserControl is included in the main page as "userControl1", then I would access it as "userControl1.IsAGreatCoder".

But, I was wondering if there was anyway to declare the UserControl such that all the UI controls added to it were declared as being public, that way allowing me to gain access to the actual controls in the main page (the parent).

Essentially I would like to be able do something like userControl1.IsGreatCoder.Checked instead of having to implement a property.

The reason I want to do this is that I want to have access to many more of the check-box's properties and it would be a pain to implement each one as a public property.

Forms Data Controls :: Use LinkButton Inside Gridview To Delete Selected Username

Mar 25, 2011

I have a "UserDetail" table in my "JobPost.mdf". I have a "Gridview1" showing the column from "UserDetail" table,which has a primary key "UserName". This "UserName" is originally saved using Membership class function. Now I add a "Delete" linkbutton to the GridView1. This "Delete" is not autogenerate button,I dragged inside the column itemtemplate from ToolBox. The GridView1's columns now become "Delete_LinkButton"+"UserName"(within the UserDetail table)+"City"(within the UserDetail table)+"IsAdmin"(within the UserDetail table)

What I need is that by clicking this "delete_linkButton",it will ONLY delete the entire User Entity on the same row (link by the corresponding "UserName") from the "UserDetail" table,as well as delete all information from the AspNetDB.mdf (User,Membership,UserInRole,etc). I would like to fireup a user confirm,but not mandatory. At least I am trying to make it functional in the correct way.

[Code]....

When I click "delete" on the first row, I need all the record about "ken" inside the "UserDetail" table to be removed. Meanwhile, all the record about "ken" in the AspNetDB.mdf will be gone, including UserinRole table. I am new to asp.net, so I don't know how to pass the commandargument of the "Delete_LinkButton" to the code-behind file LinkButton1_Click(object sender, EventArgs e), because I need one extra parameter "UserName". My partial code is listed below:

Forms Data Controls :: LinkButton OnClick Inside ItemTemplate Of A DataList Not Firing

Apr 14, 2010

Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:

[Code]....

However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:

[Code]....

<asp:DataList ID="listSearchResults" Border="1" BorderColor="Black"

Forms Data Controls :: Creating A Click Event Handler On A Linkbutton Inside A Templatefield

Feb 16, 2011

I would like to call a method and pass a value to it on a link button autogenerated from the database in a templatefield inside a datagrid. I don't know much about delegates

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
..
((LinkButton)e.Row.Cells[(int)eMessage.TitleColumn].FindControl("btnMessageTitle")).Click += new EventHandler(delegate { viewSelectedMessage(this, 35); });
}
void viewSelectedMessage(object sender, int messageID)
{
lblTest.Text = messageID;
}

running the website and viewing the page source, I have realised that there is an OnClick event created for the linkbutton, however, this may be generated anyways. By running my solution using VS debugging, I can see that my method won't fire by clicking any of thos generated linkbuttons.
