i try to make a search part. there is a textbox which will be used for search context. also, i need to list category names. i don't use dropdownlist because its styles(for example border-style)doesn't change. So i tyr to do like this:i use a label and datalist. when clicking the label, datalist is showing. when i click the category name on datalist, it will be shown on label.(label is not in datalist.)my problem starts at that point. when i click category name on datalist , page is being postback. so i put datalist into updatepanel. but this time , i click category name on datlist,nothing occurs.(category name doesn't shown on label).my code is below:
I need to input nested data (data entry) and i am using datalists for the same. The details include many details and I am managing the same using controls for each in information.The parent datalist can have max 20 rows with 7 rows in each child datalist. I tried to bind the datalists with max rows, due to which the rendered page size was almost 12MB and it took more than 2 mins to load.Alternative to this, I put the parent datalist in updatepanel and bound it to one row initially. Onclick of add button, i implemented an asynchronous postback to add new row to the parent datalist datasource and update the updatepanel to display the datalist. The new row is displayed properly in datalist, however it gets reset to original datalist after some seconds.
I have a UpdatePanel which is having a Datalist inside it , and in datalist i have a country dropdownlist whose autopostback = true , now it is causing postback which i want to trigger , but i am unable to set it as AsyncPostBackTrigger inside update panel because update panel won't find the dropdownlist as it is in datalist.
I have a datalist. When a user clicks a button in the datalist I change some properties and then want to refresh the datalist. However, the code below doesnt seem to refresh the datalist. Once I reload the entire page (which I dont want) the changes are visible in the datalist. I also tried setting the updatemode of the updatepanel to "Conditional" and update manually in the dlPhotos_ItemCommand, but that doesnt work either.
In bold I've marked where I want to refresh the datalist
I have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.
I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?
i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.
I am using two Updatepanels in ASP.NET AJAX and as soon as there is some event in first updatepanel, it will get refreshed at that time I want my second Updatepanel getting refreshed too. How can I do that ?
I have a page that has a updatepanel around a gridview control that is within my modalpopup. So you land on the page, there is a link that when clicked will open the model popup. Initially the gridview merely displayed saved records you personally choseto save, well when you selected one, the popup would close and the data from that row would be passed to the gridview within the page to display details.. no issue when it was setup that way.. well eventually it was decided to add a delete option within themodal popup gridview so now when viewing the records you can delete it if not needed. works well.. but now with the updatepanel surrounding the gridview when i click on my "select" link it doesnt execute my
I am using UrlRewritting in my project. all functionality is working proper but I cant use the ASP.NET Ajax like updatePanel etc. the problem is ScriptResource.axd file is missing (404 Error). I used lot of ASP.net Ajax control before using UrlRewritting so I cant change the whole code.....
how can I enable ASP.NET Ajax? have any Alternative to replace ASP.NET Ajax without changing in codebehind.
Say you have a Grid which is having paging, editing and extra, I usually put the whole grid in UpdatePanel to make the page partially render with AJAX, but I hear that u can do AJAX without UpdatePanel, how is that?
I try I cannot seem to find a satisfactory solution. As far as I can tell from the documentation a ModalPopupExtender should be able to reside inside an UpdatePanel. However, I simply cannot get it to work.After the first refresh of the UpdatePanel I get errors of various kinds depending on what I've tried.
What I'm trying to accomplish is having a button inside an UpdatePanel which launches a popup. Another button inside the UpdatePanel causes a partial postback. And finally a button within the popup has to cause a partial postback. I have tried at least five different approaches to this problem and finally I gave up and went with a very inelegant solution. I don't think my requirements are all that strange, am I doing something wrong?
First I tried this:
I get following error when I click on the button.I am Using IE 7.0 and Updatepanel control for AJAX in the aspx page (Not in master Page).This error goes After I clear cache.
"Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' <!DOCTYPE html PUB'."
I know this may be easy, but I have looked at it for a bit of time and maybe my brain is going in circle.OK, I am learing PopupControlExtender. Looks like it is a good thing to have. One (style of) example is to have a TextBox. Click on it and the PopupControlExtender will come up. Sample code may be like the Example 1 in this
Why there is a need to put UpdatePanel inside the Panel? It is the TextBox which needs to be updated. Why the TextBox is not put into an UpdatePanel? (I try Example 1 and it works without having to put the TextBox inside an UpdatePanel.)
