Forms Data Controls :: How To Find And Assign A Value Of Something To A Label Nested In DataList
Aug 10, 2010
I am trying to find the text property of a label that is nested within a DataList within a FormView. The FormView and the DataList have different datasources.
What I actuallt need to do specifially is assign the number of rows in the DataList to the Label in the DataList. I used the code below to find it but it keeps giving me an error about not finding the object;
I am using datalist where i need to assign my label value to each checkboxlist item.I am using datatable to bind my checkboxlist. when I run my code I can see the values in my local window. Actually not displaying in webpage.
Is there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.
I have a Datalist and when a button is clicked I would like to send the values of the fields to a new page to fill some text boxes. What is the best way to do this. I had thought that since the DataList had itemtemplates that were labels I could reference them like regular labels ( str = Label1.text ). That isn't working. I was just going to send the values through a query string. Which I have an example of that, unless there is a better way.
Here I've a listview control whose datasourceid is set to one sqldatasource, listview contains a panel in a itemtemplate region. In the panel there are some lables which are bounded to the column present in sqldatasource. But In one label I have to assign some other value dynamically. can any body tell me how to access that label and assign value to it. Here's the code
I have got DataList1 which contains DataList2And inside DataList2, I have placed control - CheckBox1How do i make CheckBox1 to be identified in CheckedChangedEvent
I'm using nested datalists as per my requirement, in my second datalist i need to show data in tab panels. For that i placed ajax tabcontainer in my second datalist <Item Template> tags.when i'm trying to access tabcontainer activeindex changed event on my code behind, i'm getting an error . Below is my code..
I have Datalist control in my application which contains one Gridview control as a child control in it. Now at the time of giving datasource to the child control, it gives object reference error.Note:I am binding the child grid at the time of ItemDataBound Event of Datalist controlMy code looks like :
i have a parent gridview,It has child gridview in every row.The edit and delete event of this child is working is fine.When i add data to through child gridview with empty data template.i can 't find the value of the parent contril id.
gvProductFeatures is the chid gridview... protected void gvProductFeatures_RowCommand(object sender, GridViewCommandEventArgs e) { try { if (e.CommandName.Equals("EmptyAddNewFeature")) { GridView gv = (GridView)sender; if (gv != null) { // here i need find the appropriate control id from parent..how?? int intIndex = Convert.ToInt32(e.CommandArgument); Label lblEmptyGroupPK = (Label)gv.Controls[0].Controls[0].FindControl("lblEmptyGroupPK"); TextBox txtEmptyFeatures = (TextBox)gv.Controls[0].Controls[0].FindControl("txtEmptyFeatures"); } } } catch(Expection ex) { } }
I have a gridview with a nested placeholder in each rows. I nested some checkboxes in each placeholders in each rows dynamically, so their ServerIDs are not the same (I dont want to use nested gridview). at the end in a button event I want to count checked checkboxes in gridview while I can not use findcontrol() method in each rows to find checkboxes due to their different ServerIDs.
i have a search control that is displaying records in a datalist. i want to add a label that shows the result of a sql aggregated function (count) using the code behind against a value that is on each datalist. i cant seem to get that label value (courseID) from the datalist to string so this query can work.here is my code, th3 second is incomplete that is where i'm struggling.
i am using a datalist to show records that are each displayed in a table. i created a button to insert relevant data from a selected record into a new record, but there is a problem i am encountering every time a user selects a record from the datalist search query the value courseID from the first record is inserted instead of the courseID of the selected record.
I want to put sql data into several labels. For example I have a table with several labels: label1, label2, label3. The sql query will only display ONE result. (e.g. SELECT Room_ID, Room_Name, Room_Capacity FROM Rooms WHERE ROOM_ID = "112") How can I assign Room_ID to label1, Room_Name to label2, Room_Capacity to label3?
In my gridview, I have 6 columns. The first 5 columns are filled with data retrieved from database.In the 6th column I want to display a value from textbox from same form. The value should be displayed on the row next to last row of rest of the columns. So my last column (i.e.) 6th column will just have all the rows filled with the same value of the text box.
First 5 columns of grid will be filled by selecting the college name from dropdown.The last colum (Date) must be filled with the date that is given in the textbox.It can be even after button click event(date of attendence).
Im using Nested DataList in My Application. But i m not able to find control Inside Child DataList. (I want to Find Label Control In ItemDataBound Of ChildDataList)
Protected Sub DataList1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles DataList1.ItemDataBound lblshippingoutside.Visible = Dim lblshippingoutside As Label = CType(e.Item.FindControl("lblshippingoutside"), Label)False End Sub
Throws an exception .
Object reference not set to an instance of an object.
